Professor Roger Ap\`ery , a prominent figure of the University of CAEN (France),passed away after a prolonged illness on December 1994. Roger Ap\`ery was born in ROUEN in 1916 of a mother of Flemisch origin and a Greek father who had volunteered to serve in the French army in 1914 in order to obtain French nationality. After brilliant studies at the "Lycee Louis Le Grand" where he distinguished himself several times in the "Concours general" , Roger Ap\`ery was placed second among entrants at the ENS in 1936 and came first at the "Agregation de Mathematiques". Called up for the army in 1939 and a prisoner of war in June 1940 , he was released in October 1941 for health reasons. Appointed assistant lecturer at the Sorbonne in 1942 , he joined a group of ENS students in the French Resistance and became the leader of the National Front at the ENS. In 1947 he defended his thesis in algebraic geometry " a l'italienne" under the supervision of Paul Dubreil and was appointed Lecturer at Rennes (the youngest ever in France). From 1949 until he retired in 1986 , Roger Ap\`ery was a Professor at the University of CAEN where he created a research team on algebra and number theory. At the end of his career in 1977 , he made a sensational discovery which was to make his name famous throughout the world. His proof of the irrationality of the sum of the inverse of the cubes of integers by an exceptionally clever method worthier of his Greek ancestors than of Bourbaki, made him a legend. In addition to a keen sense of provocation,Roger Ap\`ery enjoyed playing the piano - his mother had taught him , chess,philosophy and ... politics. Having joined the Camille Pelletan Radical Party at a young age after the riots of 1934 , he resigned after Munich.Then , at the end of the war,he once again became an active party member with Pierre Mendes-France. As president of the Calvados Radical Party in the 60's he remained active in politics until May 68. Being opposed to the reforms instituted after 68 by Edgar Faure , he abandoned political life when he realized University life was running against the tradition he had always upheld. Many researchers have worked with the so-called Ap\`ery sequences to rediscover his proof of the irrationality of Zeta(3)( See H.Cohen,A. Van Den Poorten, E.Reyssat,F.Beukers,M.Prevost), to generalize his recurrence relation in connexion with Numerical Analysis and Orthogonal Polynomials ( R.Askey,J.A. Wilson,A.L.Schmidt) or to study the congruence properties of Ap\`ery numbers ( P.T.Young,Y.Mimura,I.Gessel,S.Chowla). (From a text by Y. Hellegouarch). ------------------------------ From: Fred J. Hickernell Date: Mon, 19 Jun 1995 21:38:55 +0800 (EAT) Subject: An Electronic Abstract Server? Has anyone considered setting up a listserver that would broadcast abstracts of new results to interested recipients? One would subscribe by giving one's name, e-mail address and the AMS classification codes corresponding to one's areas of interest. When an abstract was received by the server, it would be broadcast to those on the mailing list with the corresponding classification codes. The abstract could also give the location of the full preprint for downloading. Does such a server already exist? If not, is there interst in setting one up? Would the na-net, SIAM, AMS or some other group consider it? I would be interested to hear others' opinions. Fred J.

The algorithms may be sequential, distributed, or parallel. They may be analyzed either mathematically or by rigorous computational experiments. In either case, the selection of papers will be based on the extent to which the results yield new insights for the design of efficient algorithms. The program committee especially encourages submissions which report on experimental and applied research. Special consideration will be given to work that is motivated by real-world problems. Experimental and applied papers are expected to show convincingly that the algorithms or data structures discussed are useful and efficient in a practical setting. Program Committee Eva Tardos (Chair), Cornell University; David Applegate, AT&T Bell Laboratories; John Canny, University of California, Berkeley; David Eppstein, University of California, Irvine; Zvi Galil, Columbia University and Tel-Aviv University, Israel; David R. Karger, Massachusetts Institute of Technology; Anna R. Karlin, University of Washington; Nati Linial, Hebrew University, Israel; Satish B. Rao, NEC Research Institute; Jeffrey S. Vitter, Duke University; and Peter M. Winkler, AT&T Bell Laboratories Papers will be selected for presentation based on extended abstracts. Authors wishing to submit a paper should send twelve copies of an extended abstract (not a full paper) to: SIAM Conference Coordinator, 3600 University City Science Center, Philadelphia, PA 19104-2688, U.S.A. Abstracts must be received at the SIAM office by JULY 14, 1995 (or postmarked by July 12, 1995 and sent airmail). This is a firm deadline; submissions after the deadline will not be considered. Letters of acceptance/rejection will be sent by September 20, 1995. Abstract Format. Abstracts should begin with the title of the paper, each author's name, affiliation, and e-mail address, followed by a succinct statement of the problems that are considered in the paper, the main results achieved, an explanation of the significance of the work, and a comparison to past research. This material should be easily understood by nonspecialists. Technical developments, directed toward the specialist, should follow as appropriate. The entire extended abstract must not exceed 10 pages (using 11 point or larger font, with not less than one inch margins all around). Abstracts that deviate significantly from these guidelines risk rejection without consideration of their merits.

Walsh Date: Mon, 19 Jun 1995 15:21:58 +0100 (BST) Subject: Postdoc Position at University Greenwich, London Applications are invited for an EPSRC-funded Fellowship in the Nano-Science Simulation Group to investigate a multi-level, unified, modelling of fracture physics in adhesive joints. Such an approach will involve a unified, computer-based, simulation of materials properties at the nano, micro and continuum scales. Both deterministic and stochastic Molecular Dynamics (MD) simulation strategies will be employed to gain insights into the initial formation and propagation of cracks at the atomistic level. The micro- and macro-scale behaviour of these nano-scale cracks will be studied via continuum theories of fracture mechanics. Applicants should have a strong basis in the application of atomistic and molecular simulation methodologies in materials science/condensed matter physics and be prepared to extend their expertise into the continuum-scale modelling of material processes. The post is initially for a 2 year duration, starting from September 1995, with the possibility of further extension at the salary of 19000 Pounds per annum.
