Hales from the University of Michigan has been using interval computations in his reasearch on the Kepler Conjecture (on the densest arrangment of spheres in space). This is a work-in-progress; preliminary results, preprints, and references can be found at the following URL: http://www.math.lsa.umich.edu/~hales/kepler.html This information can also be accessed from the Applications part of the Interval Computations website http://cs.utep.edu/interval-comp/main.html. ------------------------------ From: APMATH Date: Mon, 30 Dec 1996 17:03:26 +0200 Subject: General Iterative Solver APMATH announces the release of General Iterative SOLVer (GISOLV). This package is based on new iterative algorithm for solving large scale, general linear systems. It eliminates, almost completely, the stagnation phenomenon related to GMRES-like algorithms. One can find the package in http://www.apmath.com ------------------------------ From: G. W. Stewart Date: Thu, 2 Jan 1997 14:53:02 -0500 (EST) Subject: More Afternotes on Numerical Analysis Recently I published a collection of lectures entitled Afternotes on Numerical Analysis. The unusual name reflects the unusual way they were produced. Instead of writing the notes and giving the lectures, I gave the lectures and then wrote the notes\,---\,in real time, two lectures a week. In preparing the notes I hoped to bring the immediacy of the classroom to the printed page and give an uncluttered presentation that could be used for self I have just completed a new set of afternotes and have posted them on the web. The original afternotes were based on an advanced undergraduate course taught at the University of Maryland. The present notes are based on the follow-up graduate course. The topics treated are approximation\,---\,discrete and continuous\,---\,linear and quadratic splines, eigensystems, and Krylov sequence methods. The notes conclude with two little lectures on classical iterative methods and nonlinear equations The notes may be obtained by anonymous ftp at thales.cs in /pub/afternotes| or by browsing my homepage http://www.cs.umd.edu/~stewart/. I will be grateful for any comments, corrections, or suggestions. Pete Stewart ------------------------------ From: William Mitchell Date: Thu, 2 Jan 97 13:31:41 EST Subject: StopWatch Version 1.0 Available I am pleased to announce the availability of StopWatch Version 1.0. StopWatch is a Fortran 90 module for measuring execution time of program segments. It is designed to be a portable, easy-to-use means of measuring execution time. It supports the wall clock, CPU clock, a breakdown of the CPU clock into user and system times, and returns all times in seconds. It provides a simple means of determining which clocks are available, and the precision of those clocks. StopWatch is used by instrumenting your code with subroutine calls that mimic the operation of a stop watch. The primary routines are start_watch, stop_watch, reset_watch, read_watch and print_watch. StopWatch supports multiple watches, and provides the concept of watch groups to allow functions to operate on multiple watches simultaneously. The StopWatch package includes the source code for the StopWatch module, several example programs with makefiles for many computational environments, a user's guide in postscript and html formats, and man pages. This is version 1.0 of StopWatch. It has been tested with NAGWare F90 (SunOS 4.1.3, Linux and HPUX), EPC Fortran 90 (SunOS 4.1.3), Digital Fortran 90 (Digital UNIX), CF90 (UNICOS), XLF (AIX), HP Fortran 90 (HPUX), Absoft F90 (MacOS), Fujitsu Fortran 90 (Solaris), Sunsoft F90 (Solaris), F (Linux, AIX), and Lahey Elf90 (Windows NT). The User's Guide and StopWatch package can be accessed through WWW at the URL http://math.nist.gov/StopWatch The StopWatch package can also be obtained by anonymous ftp to math.nist.gov in /pub/mitchell/stopwatch/stopwatch-1.0.tgz. This is a gzipped tar file. William F.

Neptune Hotel, Eilat, Israel Workshop Organizers: Secretary: Achi Brandt, Weizmann Institute Carol Weintraub Gerhard Mack, Hamburg University Office: 972-8-9343545 Sorin Solomon, Hebrew University Fax: 972-8-9344122 WWW: http://shum.cc.huji.ac.il/~sol/eilat/eilatcon.html The nature of the interactions between different scales of phenomena in a complex system is the focus of interest in an increasingly wider range of scientific fields. This interest originated independently in theoretical physics and in computational mathematics. Like the first Eilat workshop (February, 1995) the purpose of this second one is to bring together different communities of researchers having the common interest of studying the different ways in which inter-scale interactions occur in nature and can be devised and exploited in calculations. This time, computational chemistry will be added as one of the main themes. The participants include computational physicists, chemists and mathematicians. The physicists are mainly from the field theory and statistical mechanics communities, especially in the theoretical and/or simulation aspects of renormalization group, criticality and universality, with interest in the more general theory of dynamical and complex phenomena and/or in their computational aspects. The chemists bring special interest in ab initio quantum calculation and in large scale molecular dynamics. The participating mathematicians will represent several research communities which have adopted different versions of multiscale scientific computation: multigrid, multipole, hierarchical bases, wavelets, and other relatives. More information about the workshop, its scientific background, mode of organization and location, including details on travel, climate, prices, accommodations, services, social program, etc. is available at the above Web site, together with registration, accommodation and travel forms. This information can also be received via email, fax or regular mail by request from the conference secretary: Carol Weintraub, Department of Applied Mathematics and Computer Science, Weizmann Institute of Science, Rehovot 76100, Email: carol@wisdom.weizmann.ac.il, Tel: +972-8-9343545, Fax: +972-8-9344122. Because time is short, hearing soon from anybody who intends to participate would be appreciated. The number of rooms in the hotels at the conference rate is, unfortunately, limited, so it is advisable to complete the accommodation forms as soon as possible. ------------------------------ From: dvw-AWM Date: Thu, 2 Jan 1997 18:07:21 -0500 (EST) Subject: AWM WORKSHOP AT SIAM MTG, JULY 1997 Application DEADLINE for the AWM Workshop for WOMEN Graduate Students and Postdoctoral Mathematicians at the SIAM Annual Meeting Stanford University, Stanford, Calfornia July 13-15, 1997 is MARCH 1, 1997 Applicant who meet eligibility requirements and are selected to participant in the AWM Workshop will received reimbursement for FULL transportation costs, registration cost to the SIAM Annual Meeting and 2 days subsistence for meals and lodging.
