    ROUGH SETS and CURRENT TRENDS in COMPUTING RSCTC'9B Ist1st International Conference June 22-26 Warsaw Poland Professor Edward A. Feigenbaum 7 Stanford University Stanford CA 94305 USA Dear Professor Feigenbaum, on behalf of the organizers, including Professors Pawlak and Skowron, I have the privilege to express our thanks for Your accepting our invitation to act as a Honoraryco-Chair of our Conference. Enclosed please find a copy of the First Call for Papers. With our deepest regards, Sincerely Yours, Lech Polkowski Chair, Organizing Committee - * Rough Set Theory, proposed first by Zdzislaw Pawlak in the early 80's, has recently reached a maturity stage. In recent years we have witnessed a rapid growth of interest in rough set theory and its applications, worldwide. Various real life applications ofrough sets have shown their usefulness in many domains. It is felt useful to sum up the present state ofrough set theory and its applications, outline new areas of development and, last but not least, to work out further relationships with such areas as soft computing, knowledge discovery and data mining, intelligent information systems, synthesis and analysis of complex objects and non-conventional models of computation. Motivated by this, we plan to organize the Conference in Poland, where rough set theory was initiated and originally developed. An important aimof the Conference is to bring together eminent experts from diverse fields of expertise in order to facilitate mutual understanding and cooperation and to help in cooperative work aimed at new hybrid paradigms possibly better suited to various aspects of analysis ofreal life phenomena. We are pleased to announce that the following experts have agreedto serve in the Committees of our Conference.

    Comments on [5], [14], [22], [30], and [31] Donald L. Burkholder Department of Mathematics University of Illinois Urbana, IL 61801 [email protected] During the two decades after the publication of the pi- oneering papers Proof of the ergodic theorem and Proof of the quasi-ergodic hypothesis by Birkhoff [Bi] and von Neumann [vN], but before the publication of A general ergodic theorem by Calder´onin 1953, there were new proofs and generalizations of the results of Birkhoff and von Neumann given by many mathematicians. These in- clude, among others, Khintchine, Hopf, Kolmogorov, F. Riesz, Yoshida, Kakutani, Wiener, Dunford, Pitt, Doob, and Zygmund. Much of this substantial body of work is referenced in [Ho2], [Ka], and [Kr]. Explorations in many new directions have continued since then and have greatly expanded the connections and applications of er- godic theory to other parts of mathematics and beyond. Calder´on's1953 paper [5] played an important role in this development. In the paper, Calder´onstudies the behavior of averages of the form 1 Z F (gx) dg: (1) Nt j j Nt Here (Nt)t>0 is a family of compact symmetric neigh- 1 borhoods of the identity of a locally compact group G of one-to-one measure-preserving transformations g on a measure space E of finite measure, Nt is the left in- j j variant Haar measure of Nt with dg denoting an element of this measure, and F is an integrable function on E such that (g; x) F (gx) has appropriate measurabil- ity. It is not assumed7! that G is abelian but it is as- sumed that G is ergodic in the sense that there exists a family (Nt)t>0 as above satisfying NtNs Nt+s and ⊂ N2t < α Nt with the choice of the constant α not de- pendingj j onj tj.

Abstract: Solomon Marcus (1925–2016) was one of the founders of the Romanian theoretical computer science. His pioneering contributions to automata and formal language theories, mathematical linguistics and natural computing have been widely recognised internationally. In this paper we briefly present his publications in theoretical computer science and related areas, which consist in almost ninety papers. Finally we present a selection of ten Marcus books in these areas. Keywords: automata theory; formal language theory; bio-informatics; recursive function theory 1.

That is why the short presentation below is by no means complete, it is only a way to pay our homage to him at his 85th birthday anniversary.

  • The Perspectives of Scientific Research Seen by Grigore C
    THE PERSPECTIVES OF SCIENTIFIC RESEARCH SEEN BY GRIGORE C. MOISIL FORTY YEARS AGO EUFROSINA OTLĂCAN* Motto: “There are people whose contribution to the progress of mankind is so great that their biography is put into the shade, the life is hidden away by the work”. (Gr. C. Moisil at the W. Sierpinski’s death) Abstract. The creation, the personality and the entire activity of the Romanian mathematician Grigore C. Moisil (1906–1973) are illustrative of the idea of universality in science and cultural integration. Moisil obtained his degree in mathematics at the University of Bucharest and became a PhD in 1929, with the thesis “The analytic mechanics of continuous systems.” The three years of courses at the polytechnic school did not finalize with an engineer diploma, they only meant an opening towards the understanding of technical problems. The scientific area of Moisil’s work covered, among other domains, the functional analysis applied to the mechanics of continuous media, to differential geometry or to the study of second order equations with partial derivatives. One of the most original parts of Moisil’s creation is his work in mathematical logic. Within this frame Moisil developed his algebraic theory of switching circuits. By his theory of “shaded reasoning”, G. C. Moisil is considered, besides L. Zadeh, one of the creators of the fuzzy mathematics. Apart from his scientific and teaching activities, Moisil was a highly concerned journalist, present in many newspapers and on television broadcasts. Keywords: Grigore C.

  • Turing and Von Neumann's Brains and Their Computers
    Turing and von Neumann’s Brains and their Computers Dedicated to Alan Turing’s 100th birthday and John von Neumann’s 110th birthday Sorin Istrail* and Solomon Marcus** In this paper we discuss the lives and works of Alan Turing and John von Neumann that intertwined and inspired each other, focusing on their work on the Brain. Our aim is to comment and to situate historically and conceptually an unfinished research program of John von Neumann, namely, towards the unification of discrete and continuous mathematics via a concept of thermodynamic error; he wanted a new information and computation theory for biological systems, especially the brain. Turing’s work contains parallels to this program as well. We try to take into account the level of knowledge at the time these works were conceived while also taking into account developments after von Neumann’s death. Our paper is a call for the continuation of von Neumann’s research program, to metaphorically put meat, or more decisively, muscle, on the skeleton of biological systems theory of today. In the historical context, an evolutionary trajectory of theories from LeiBniz, Boole, Bohr and Turing to Shannon, McCullogh-Pitts, Wiener and von Neumann powered the emergence of the new Information Paradigm. As Both Turing and von Neumann were interested in automata, and with their herculean zest for the hardest proBlems there are, they were mesmerized by one in particular: the brain. Von Neumann confessed: “In trying to understand the function of the automata and the general principles governing them, we selected for prompt action the most complicated oBject under the sun – literally.” Turing’s research was done in the context of the important achievements in logic: formalism, logicism, intuitionism, constructivism, Hilbert’s formal systems, S.C.
