3. New Books ——– R. Gorenflo, A.A. Kilbas, F. Mainardi, S.V. Rogosin, Mittag-Leffler Functions, Related Topics and Applications. Sprin- ger Monographs in Mathematics, Springer, 2014, 443 p., 7 illus., ISBN 978-3-662-43930-2. Details at: http://www.springer.com/mathematics/analysis/book/ 978-3-662-43929-6?wt mc=Alerts.NBA.SpringerAuthors-Nov-6. There the readers can download Table of Contents and Sample Pages. Annotation: – Unique project to be realized in the theory of special functions. – Presents a complete and self-contained description of all aspects of the theory and application of the Mittag-Leffler functions. – The introduced functions are of great importance for solving differential and integral equations of fractional order. As a result of researchers and scientists increasing interest in pure as well as applied mathematics in non-conventional models, particularly those using fractional calculus, Mittag-Leffler functions have recently caught the interest of the scientific community. Focusing on the theory of the Mittag- Leffler functions, the present volume offers a self-contained, comprehensive treatment, ranging from rather elementary matters to the latest research results. In addition to the theory the authors devote some sections of the work to the applications, treating various situations and processes in viscoelasticity, physics, hydrodynamics, diffusion and wave phenomena, as well as stochastics. In particular the Mittag-Leffler functions allow us to describe phenomena in processes that progress or decay too slowly to be represented by classical functions like the exponential function and its suc- cessors. EDITORIAL 5

The book is intended for a broad audience, comprising graduate stu- dents, university instructors and scientists in the field of pure and applied mathematics, as well as researchers in applied sciences like mathematical physics, theoretical chemistry, bio-mathematics, theory of control, and sev- eral other related areas.

4.ReportsonPassedEventsRelatedtoFCAA ——– Days of Analysis in Novi Sad (DANS 2014) July 03 – 07, 2014, Novi Sad, In the honor of Professor Bogoljub Stankovic on the occasion of his 90th birthday This was the first Russian – Serbian mathematical meeting within the framework of scientific cooperation of Russian and Serbian academies of sciences and arts. Around 60 mathematicians from Austria, Brazil, Bul- garia, , , Italy, Macedonia, Monte Negro, Norway, Russian Federation, Serbia, Sweden and United States attended the conference. It was organized with the aim of gathering mathematicians in order to establish fields of research of joint scientific interest. The conference was held at the Department of Mathematics and Informatics, Faculty of Sciences, of Novi Sad University. The scientific program consisted of 40- minute talks, 20-minute communications, and a poster session. Plenary lectures were given by: S. Pilipovic (Serbia), L. Rodino (Italy), M. Oberguggenberger (Austria), A. Ivic (Serbia), G. Milovanovic (Serbia), T. Atanackovic (Serbia), S. Coriasco (Italy), D. Abreu (Portugal), M. Kun- zinger (Austria), G. Hoermann (Austria), R. Steinbauer (Austria), J. Toft (Sweden), T. Gramchev (Italy), D. Djordjevic (Sebia), V. Dragovic (Ser- bia), P. Ivanishin (Russian Federation), M. Mateljevic (Serbia), D. Stoeva (Bulgaria), N. Antonic (Croatia), V. Kapustin (Russian Federation). The conference was organized at Department of Mathematics and Infor- matics, Faculty of Sciences, University of Novi Sad. Organizing Committee: Stevan Pilipovic (University of Novi Sad), Nenad Teofanov (University of Novi Sad), Vladimir Kapustin (St Petersburg Dept. of Steklov Institute of Mathematics), Nada Aleksic (University of Novi Sad, secretary). ——– At the ceremony in honor to Professor Bogoljub Stankovic, the following speach was presented: Distinguished guests, Rector, Dean, Academicians, Colleagues, I am very much honored to open this meeting devoted to the 90 years of Academician Bogoljub Stankovi´c. During his 90 years he was a witness of the historical development of our country that has changed its name 6 or 7 times during his life time (Still, history goes on). He was born in 1924. in a village of Botoˇs, and finished his primary and grammar school in Novi Sad. As a participant in the resistance movement against occupying forces, he was arrested in 1944. He welcomed the freedom in Dachau Concentration Camp. EDITORIAL 7

Prof. Stankovi´c began his studies of mathematics at the Belgrade Uni- versity, in 1945, and graduated in 1949. The same year he became an assistant professor at the Mathematical Institute of the Serbian Academy of Sciences and Arts, where he received his PhD Degree in 1954 under the supervision of Academician Vojislav Avakumovic. In this 1954 he was one of the founders of the Faculty of Philosophy in Novi Sad and its Department of Mathematics. Actually, he was one of the founders of the University of Novi Sad where he formally finished his teaching carrier in 1990. Prof. Stankovi´c was elected as a corresponding member of the Serbian Academy of Sciences and Arts in 1963. At present, he is not the oldest academician but the one with the longest academic status in the Serbian Academy of Sciences and Arts. During his professional carrier he has been Rector of the University of Novi Sad, Dean and Vice Dean of the Faculty of Natural Sciences, Director and Head of the Department of Mathematics. Prof. Stankovi´c has been an eminent representative in Yugoslav institutions and delegations in several world conferences related to culture, education and science. His contributions were recognized by the state and crowned by the most prestigious awards and honors of this country (with different names) for his work in Research, Education and Culture. Long life and a great carrier! Let me continue with the science. His main contributions belong to the theory of Mikusinski’s operators, generalized integral transforms, generalized asymptotics and Abelian and Tauberian type theorems. At present he uses his knowledge in the mathe- matical justification of various type of fractional order equations. Professor Atanackovic will say something about that tomorrow. (I did this for Taube- rian theorems this morning.) The main mission of Professor Stankovi´c can be stated in one sentence: He was the founder of modern mathematical analysis in Serbia. After the Second World War there has been a strong group working in mathematical analysis led by Academician Jovan Karamata. Profes- sor Stankovi´c was a member of this group, but he started to work in the abstract operational calculus with applications in the theory of partial dif- ferential equations, influenced by the strong France mathematical school during his stay in for almost two years. Let me just mention that many fields of functional analysis, mainly related to generalized functions, were developed in Yugoslavia and later Serbia only here in Novi Sad. He was strong enough and brave to enter into totally new fields of functional analysis and then to work in these fields with his students and to produce new interesting results. For example, in order to produce a new Tauberian type theorems we jointly entered into a delicate and very rich theory of hy- perfunctions, totally new for all of us at that time. Generally, in this way 8 EDITORIAL he founded and developed the so-called Novi Sad school of mathematical analysis. He was the founder of the mathematical analysis seminar and has been its leader for 51 years now. In this period, all of us, his students, have followed the PhD programs created by him as the members of this seminar. He invited many good mathematicians as guests within the seminar. We, students and later professors, have presented our first results, new ideas and interests in our scientific work at this seminar. He got us motivated, encouraged us to persevere in the work and gave important advices on how and what to do, what to read, where to go - all in order to develop our mathematical education. Prof. Stankovi´c has established strong scientific cooperation with many mathematicians around the world. Especially, he was one of the founders of conferences on generalized functions – today known as GF conferences. (This year in Souhampton.) The first one was organized in Poland (1963) and the second one in Yugoslavia (1964). Together with him we have organized several such conferences in Novi Sad. Two years ago we have established an International Association for Generalized Functions with its headquarters in Vienna, led by Professor Michael Oberguggenberger. Personally I learnt a lot from Professor. He directed my work and enabled several of my visits to important mathematical centers in Katowice, Moscow and Innsbruck at the beginning of my carrier. He supported me and sometimes advised me in the cases of my, from time to time, not well articulated protests. I have heard from him many interesting details of his life, difficult periods during the Second World War, his activities after that war, stories about our great mathematicians. We are working together for more than 40 years. All that time with deep respect and pleasure. This has been a great privilege for me. Thank you for that. Stevan Pilipovi´c, Professor at University of Novi Sad, Full member of Serbian Academy of Sciences and Arts July 3, 2014 5. 90th Anniversary of Prof. Bogoljub Stankovic – Honorary member of Editorial Board of “FCAA”, Full Member of Serbian Academy of Sciences and Arts Academician Bogoljub Stankovi´c was born on 1 September 1924 in a village of Botoˇs, in the county of Zrenjanin, and finished his primary and grammar school in Novi Sad. When the war started he was in the sixth form of the grammar school. In June 1944 he was arrested by the Hungarian secret police and had been to many camps in Hungary and . At the time when the war ended he was in Dachau Concentration Camp. He began his studies of mathematics at the Faculty of Philosophy in Belgrade in 1945 and graduated in June 1949. During the last year at the Faculty he received a grant from the Serbian Academy of Sciences and Arts. EDITORIAL 9

In 1949 B. Stankovi´c was elected assistant professor at the Mathemati- cal Institute of the Serbian Academy of Sciences and Arts, where he received his PhD Degree in 1954. When the Novi Sad Faculty of Philosophy and its Department of Mathematics were founded in 1954, the Faculty’s Main Committee chose him to be one of its first professors. Therefore, since the Department’s early beginnings, he took part in the organization and performance of teaching as well as in the preparation of students for the research work. He was the founder of the mathematical analysis seminar and has been its leader for 51 years by now. Nearly all professors of math- ematical analysis have been through this seminar. In 1959, he was elected associate and in 1964 as full professor. He retired in 1990. He was elected a corresponding member of the Serbian Academy of Sciences and Arts in 1963 and in 1972 he became its full member (Academician). He was elected also a full member and the first president of the Vojvodina Academy of Sci- ences and Arts in 1979. Academician Bogoljub Stankovi´c occupied various functions at the University and Faculty. He was Head of the Department of Mathematics of the Faculty of Natural Sciences in Novi Sad, Dean and Vice-Dean of the Faculty, Director of the Institute for University Teaching of the University in Novi Sad, Director of the Mathematical Institute of the Faculty of Natural Sciences in Novi Sad and he served as Rector of the University of Novi Sad for one term. He is married and has two daughters. He speaks English and French fluently, and also has some knowledge of German, Russian and Hungarian. Teaching career: It is connected with the Faculty of Philosophy, i.e. the Faculty of Nat- ural Sciences in Novi Sad. As its first professor of analysis at the Depart- ment of Mathematics he had the pleasure of taking part in preparation and adaptation of school curricula from the Department’s earliest beginnings. He was teaching on all subjects in the field of analysis and its applica- tion, and supervising the three year study programmes until his retirement. Academician Stankovi´c paid particular attention to modernization of the teaching process and planning of teaching units. In the polls conducted among students, he had always been rated with the highest scores for the lectures he held. He was invited to the University of Paris to teach General Mathematics during 1959/1960 school year. He also gave lectures by invitation at the universities in , Budapest, Szeged, Debrecen, Kuwait, Allahabad (in India), Brisbane (in Australia), etc. Prof. Stankovi´c supervised more than 15 doctoral theses of candidates from the country and abroad and also gave his opinion in writing for several foreign doctoral theses. 10 EDITORIAL

Scientific work: On the initiative of Polish mathematicians and the Mathematical In- stitute of the Polish Academy of Sciences in Katowice, the researchers in the field of generalized functions gathered at scientific meetings always in a different country. The first meeting was held in Poland in 1963, and the second in Yugoslavia (in the town of Srebrno). By now such meetings were held in the Soviet Union, Bulgaria, Hungary, the German Democratic Re- public, India etc. Three more meetings were held in Yugoslavia (in 1987 in Dubrovnik, in 1996 and 2004 in Novi Sad). The most eminent mathemati- cians in this field from all over the world, from Japan to North and South America, took part in these meetings making possible to keep up with the latest results in this field. Academician Bogoljub Stankovi´c was among the initiators of all these meetings and invited to deliver lectures there. Their proceedings were published by the world leading publishers (Plenum Press, World Scientific, etc.) or in international journals (Integral Transform and Special Functions, Uspehi Matematiˇceskih Nauk, etc.). In addition, academician Bogoljub Stankovi´c was invited to take part in a number of other meetings in Hungary, Poland, Germany, Russia, India, Kuwait, Australia and Yugoslavia. He also delivered lectures at almost all world congresses that were held during his scientific career as well as at all Yugoslav congresses of mathematicians. Through joint projects with the Institutes of the Soviet Union Academies of Sciences, Poland and Bulgaria, Prof. Stankovi´c contributed to connecting Yugoslav researchers with the great research centers in the world. He was also the leader of the project financed from the common USA - YU fund (1985-1988 and 1989-1992). That was the first project in former Yugoslavia accepted to be financed by the American National Science Foundation. Academician Bogoljub Stankovi´c has been a member of the Editorial Board of a number of journals published in the country and abroad, as well as of several Proceedings of international meetings. Other activities: Academician Bogoljub Stankovi´c used to be a member of the Mathe- matical Society of Yugoslavia and is now a member of the American Math- ematical Society and the Mathematical Society of Serbia. He had long been a member of the Executive Committee of the Society of Mathematicians, Physicists and Astronomers of Yugoslavia, of the Balkan Mathematical Union and of the European Mathematical Society. Academician Bogoljub Stankovi´c has been involved in many social ac- tivities. Just to mention some of them: member of the Council for Ed- ucation and Culture of the Federal Assembly; member of the Executive Committee of the Inter-Parliamentary Union - its Board for Yugoslavia EDITORIAL 11

(1969-1974); also a representative of his country at the Inter-Parliamentary Union Conference in Caracas and Vice-President of the Presidency for Inter- Parliamentary Union Conference on Mediterranean Sea Pollution in Rome in 1974. He was in a three-member Yugoslav delegation that visited the countries of South America, Caribbean Area and Washington (within the Inter-Parliamentary Union).
