The recent publication activities include “Diabesity: The Unacknowledged Indian Knowledge”, “Jivanayanam lo Rasayanalu “ and “21st Century Noble Awards in Chemistry”. As a part of its continued efforts in this direction, a Special Issue of the Proceedings of the Telangana Academy of Sciences entitled ''Frontiers In Mathematics'' has been brought out now with Prof. B. Sri Padmavati, School of Mathematics and Statistics, University of Hyderabad as a Guest Editor. This issue contains different research topics of Mathematics with leading authors drawn from different national and international Centers of Excellence including California Institute of Technology, Emory University of USA, besides premier institutions like TIFR, Chennai Mathematical Institute, University of Hyderabad, IIT Delhi- Kanpur- Palakkad-Kharagpur-Hyderabad , University of Mumbai, Indian Statistical Institute, Kolkata. I hope this Proceedings will serve as a pace setter for detailed investigations in Mathematics and Applied Mathematics and be beneficial for the young researchers in the field and also for aspiring mathematicians. I express my gratitude to Prof. B. Sri Padmavati, Guest Editor of the special issue and to Prof. S.M. Reddy, Editor of Publications for bringing out such an excellent special issue entitled “Frontiers in Mathematics”. S. Chandrasekhar Hon. Secretary, TAS From the Guest Editor It gives me immense pleasure to bring out this special issue of the Proceedings of Telangana Academy of Sciences entitled “Frontiers in Mathematics” as a Guest Editor. This issue includes articles by some very eminent and senior mathematicians and also by some promising young mathematicians. This issue contains and assortment of topics in mathematics and applied mathematics that will appeal to serious researchers in quest of original results, to aspiring mathematicians trying to get a flavour of some research topics in mathematics and also to those who just enjoy and love reading about mathematics and mathematicians. I thank all the authors who contributed their original results, all those who contributed expository articles and also those who wrote some other very interesting, insightful and illuminating articles for this special issue. I also thank all the reviewers who spared their precious time to send their valuable comments and suggestions to the authors. Prof. B. Sri Padmavati Guest Editor From the Editor of Publications Telangana Academy of Sciences, the erstwhile AP Akademi of Sciences, is one of the oldest of the state Academies of the country, and has been serving the cause of science in particular and society at large in a befitting manner. It has been publishing scientific documents of international, national and regional relevance since its inception in 1963. It has been publishing the official journal of the academy covering the areas of Life Sciences, Chemical, Physical, Engineering and Earth Sciences. In view of its long standing contributions, we are making earnest efforts to make it vibrant which can bring name and fame to the Telangana Sciences in particular and to India at large. India has made great strides in different fields of sciences and made remarkable efforts to realize different revolutions such as green, white, blue, yellow and rainbow which made India one among different countries in the world to become self-sufficient in agricultural products. Even though our R&D contributions in the world stand at 3.2%, no institute stands in the list of top 200 research organizations in the world, even though the contributions of some individuals are of high standard. There is a need for concerted efforts in basic research which can be translated into world class technologies. The Academy has initiated printing of special issues and books on popular sciences in which established researchers were requested to contribute for this purpose. We are now ready with some special issues including the present one on ‘Mathematics‘. I thank Prof. B. Sri Padmavati, Guest Editor, and all the contributors for their valuable articles. We also look forward to the whole hearted co-operation from the Fellows of TAS through their contributions of high quality scientific and research articles for publication in these Proceedings. S.M.
