Subject: Henrici Prize

The first Peter Henrici Prize will be presented at the ICIAM meeting
in Edinburgh in July, 1999. This Prize, sponsored by SIAM and ETHZ,
is to be given to honor Peter Henrici who was such an eminent figure
in Applied Mathematics and Numerical Analysis. In addition to all his
scientific achievements, he wrote numerous books and papers in an
elegant manner, communicating ideas coherently and logically.

The Peter Henrici Prize is awarded for original contributions to
applied analysis and numerical analysis and/or for exposition
appropriate for applied mathematics and scientific computing. The
award is intended to recognize broad and extended contributions to
these subjects, more than a single outstanding work.

The initial award has been arranged by G. Gonnet of ETHZ.

We solicit nominations for this prize. Please send your nomination
with evidence of support to by May 17, 1999.

Subject: Series Acceleration

Does anyone have a reliable subroutine for implementing the Shanks
transform (Wynn algorithm) for series acceleration? I appreciate it.
What can we do if sometimes two consecutive terms of the
series become equal?

Subject: High-order Scheme for Time-dependent Schroedinger Equation

Dear NA Experts,

Could anyone please propose me literature or program codes (preferably
FORTRAN or C) on a finite difference method for the time-dependent linear
schroedinger equation in one space dimension which is at least 3rd order
in time and conserves the mass (discrete L2 norm), like the Crank-Nicolson
FD scheme.

Thank you very much in advance,

Subject: Convection Dominated Diffusion

Dear collegues:

I have a question about convection-dominated diffusion problems.
I am implementing a new numerical scheme whose accuracy (the error
between exact solution and numerical solution in L2 norm) does not
deteriorate as the Peclet number (the ratio of convection
coefficient over diffusion coefficient) goes to infinity. That is,
the accuracy remains basically the same when the Peclet number
is 1, 10^2 (10 to the power of 2), 10^5, 10^{10}, 10^{50},
and 10^{100} on a fixed grid.

My first question is if anyone can provide me with references
showing that the accuracy deteriorates as the Peclet number
is increased for finite element, difference, volume methods and
other methods. I know standard numerical methods can perform
arbitrarily badly when convection strongly dominates diffusion,
but do not know published (or to be published) results showing this.

My second question is if anyone knows any numerical method whose
accuracy does not deteriorate as the Peclet number goes to infinity.
I would like to do a numerical comparison as part of a paper.

Subject: Test Bench for Dynamical Systems

Dear Colleagues,

We are interested in new Ordinary Differential Equations solvers,
Differential Algebraic Equations-solvers and Nonlinear Algebraic Equations
solvers that may be used for simulating hybrid systems (see below). We can
link new solvers on ones' own if you send FORTRAN text. You my do it by
yourself if you will follow our instructions about DLL structure. If you
want to compare your software with build in our tool on our test collection,
join our project.

Best regards,
Yuri. B. Senichenkov

St. Petersburg Technical University

Model Vision Studium (MVS) is the virtual test bench for modeling and
simulation of complex dynamical systems based on Object-Oriented Technology.
Hybrid Automata is used in MVS as the main mathematical model of a complex
dynamical system. The graphical form of Hybrid Automata named Behavior-Chart
is used for visual representation of a hybrid behavior. Hybrid Automata may
be described as oriented graph. Graph nodes are interpreted as local continues
activities given in a form of algebraic-differential equations. Graph
edges point to next possible local behavior. To each edge is prescribed a
predicate with given node-leaving conditions and lists of momentum actions are
taken when a node is leaving. The more general allowed form of local behavior
in MVS is a system of algebraic-differential equations, where A may be
singular, but the index of a system should be equal to one. We recommend
user to construct a Behavior-Chart thus a solved system has fixed structure
and smooth right-hand sides. The three Equation Solvers may be suggested in
this case. They are ODE-solver, DAE-solver and AE-solver. By Equation Solver
we mean a heuristic algorithm that choose the simplest numerical software for
solving a problem with user prescribed tolerance. All our Solvers are based
on available in INTERNET numerical software, namely ODEPACK, Hairer, Norsett,
Wanner and Hairer, Wanner collection, DASSEL and some others programs. The
MVS numerical library is written in FORTRAN and arranges as DLL. The main
goal of any MVS Solver is to solve automatically given numerical problem
using current information about its properties or to say user that it is
impossible. In last case user may try to solve difficult problem step-by-step
under user's control of tolerance and order of methods. The included in MVS
numerical library software has been tested on special collection. The
collection consists of linear and non-linear problems with known analytical
solutions. New test problems for ODE, DAE and AE-solvers are suggested. An
analytical solution is used for estimation of global error. MVS has two main
components that are MODEL Editor and TEST-BENCH. The test-bench gives
possibility to debug and simulate developed model. The special tools
such as "Symbolic modeling of dynamical systems", "Parametric Identification",
"Linearized model" are developing now and will be available for the users
of MVS.

Subject: New Book, Plasticity: Mathematical Theory and Numerical Analysis

New Book: ``Plasticity: Mathematical Theory and Numerical Analysis''
By Weimin Han and B. Daya Reddy
392 pp, 35 illustrations
Springer-Verlag New York
ISBN: 0-387-98704-5, Hardcover, $69.95


I. Continuum Mechanics and Elastoplasticity Theory
1. Preliminaries
2. Continuum Mechanics and Linear Elasticity
3. Elastoplastic Media
4. The Plastic Flow Law in a Convex Analytic Setting
II. The Variational Problems of Elastoplasticity
5. Results from Functional Analysis and Function Spaces
6. Variational Equations and Inequalities
7. The Primal Variational Problem of Elastoplasticity
8. The Dual Variational Problem of Elastoplasticity
III. Numerical Analysis of the Variational Problems
9. Introduction to Finite Element Analysis
10. Approximation of Variational Problems
11. Approximations of the Abstract Problem
12. Numerical Analysis of the Primal Problem
13. Numerical Analysis of the Dual Problem


The theory of elastoplastic media is now a mature branch of solid
and structural mechanics, having experienced significant development
during the latter half of this century. This monograph focuses on
theoretical aspects of the small-strain theory of hardening
elastoplasticity. It is intended to provide a reasonably comprehensive
and unified treatment of the mathematical theory and numerical analysis,
exploiting in particular the great advantages to be gained by placing
the theory in a convex analytic context.

The book is divided into three parts. The first part provides a
detailed introduction to plasticity, in which the mechanics of
elastoplastic behavior is emphasized. The second part is taken up with
mathematical analysis of the elastoplasticity problem. The third part
is devoted to error analysis of various semi-discrete and fully discrete
approximations for variational formulations of the elastoplasticity.

The work is intended for a wide audience: this would include specialists
in plasticity who wish to know more about the mathematical theory, as
well as those with a background in the mathematical sciences who seek a
self-contained account of the mechanics and mathematics of plasticity
