**Subject: Vlastimil Ptak**

The Institute of Mathematics and the Institute of Computer Science

of the Czech Academy of Sciences announce with deep sorrow that

Professor Vlastimil Ptak passed away on May 9, 1999.

Professor V. Ptak, born 8.11. 1925 in Prague, was an outstanding

world-known mathematician. Besides functional analysis his

scientific activity involved linear algebra, real analysis and its

relation to topology, combinatorics and numerical analysis. A number

of world-renowned results are due to him: a generalization of the

open mapping principle (the Ptak spaces), extensions of separately

continuous functions, investigations concerning convergence of

iterative processes, theory of critical exponents, theory of

hermitian algebras, the method of continuous induction and its

application to iterative processes. In the last years the activity

of Prof. V. Ptak concentrated around problens concerning Toeplitz and

Hankel operators, functional models and lifting of intertwining

relations. He was for a long time the Head of the Department of

Functional Analysis in the Mathematical Institute of the Academy and

supervised a number of PhD. students. He has published more than 160

mathematical research papers.

**Subject: Parallel Preconditioning: Release of SPAI 3.0**

Dear Colleagues,

We are pleased to announce the release of the new version

of SPAI: SPAI, Version 3.0.

The code can be freely downloaded at the new SPAI homepage:

http://www.sam.math.ethz.ch/~grote/spai

The SPAI algorithm computes a SParse Approximate Inverse (SPAI)

of a general sparse matrix for use as a preconditioner together

with an iterative method (Bi-CGSTAB, GMRES, QMR, etc ). The

SPAI algorithm was derived by M.J. Grote and T. Huckle (SIAM J.

Sc. Stat. Comput. 18(3), 1997), and further developed by S. Barnard.

The algorithm is robust, effective on ill-conditioned linear

systems, and inherently parallel. The code is written in C/MPI.

New features of SPAI 3.0:

- Matlab interface (M = spai(A,eps,..); )

- PETSc interface

- Block-SPAI

We sincerely hope that the Matlab and PETSc interfaces will make the

algorithm more user-friendly. The Block-SPAI feature takes advantage of

a possibly inherent block structure of the matrix, but has proved

to reduce computing time in many cases, even when no inherent block

structure is present.

The SPAI algorithm has demonstrated excellent scaling with increasing

number of processors across various parallel architectures, such as

the IBM SP2, T3E, and SGI Origin 2000 with the SHMEM library.

Best Regards,

Stephen Barnard (NASA Ames) and Marcus Grote (ETH Zurich)

**Subject: New Book, Time-Varying Systems and Computations**

NEW BOOK ANNOUNCEMENT

Title: Time-Varying Systems and Computations

Authors: Patrick Dewilde and Alle-Jan van der Veen

(DIMES, Delft University of Technology)

Publisher: Kluwer Academic Publishers, orderdept@wkpa.nl

Pages: 459

Summary: Time-Varying Systems and Computations provides a detailed

and consistent exposition of a powerful unifying framework

for the study of linear systems. Finite or infinite

systems of linear equations as well as linear dynamical

systems, be they time-varying or time-invariant, all fit in

the generic framework. The book bridges the gap between

classical linear algebra and dynamic system theory and

shows how central problems in each field can be solved

in a logically coherent way. Aside from the unifying frame,

the book treats problems in three main categories:

- System identification and realization

- Interpolation and approximation of systems

- Factorization and minimal representation.

Classical notions such as inner-outer factorization, Hankel

norm model reduction, interpolation and minimality pop

up, now in an algebraic context. They are treated in a

new, natural framework in which computations on diagonals

of a matrix or operator play the role that vectors play

in classical linear algebra. Because of this, the algorithmic

content of the book is high, justifying its title.

Content: 1. Introduction

Part I: Realization: 2. Notation and Properties of Non-Uniform

Spaces. 3. Time-varying State Space Realizations. 4. Diagonal

. 5. Operator Realization Theory. 6. Isometric and

Inner Operators. 7. Inner-Outer Factorization and Operator

Part II: Interpolation and Approximation. 8. J-Unitary

Operators. 9. Algebraic Interpolation. 10. Hankel-norm

Model Reduction. 11. Low-Rank Matrix Approximation and Subspace

Tracking.

Part III: 12. Orthogonal Embedding. 13. Spectral Factorization.

14. Lossless Cascade Factorization. 15. Conclusions.

Appendix: Hilbert Spaces Definitions and Properties.

The book is more than a research monograph, it has been carfully structured

so that it can be used as a graduate classtext.

Second International Conference on

Boundary Integral Methods:

Theory and Applications

11 - 15 September 2000 University of Bath, U.K.

This is a preliminary announcement for this conference which will be

held under the auspices of the Institute of Mathematics and its

Applications in association with the University of Bath.

Following the success of the first conference in this series at the

University of Salford in September 1997, the next meeting will be

held in Bath in September 2000.

Bath is a beautiful historic town about 2 hours West of London by rail and

with good links to Heathrow airport and the rest of the United Kingdom.

As of May 21st 1999, the following have agreed to give invited talks

at this conference:

W.C. Chew (University of Illinois), T. Hou (California Institute of

Technology), S.A. Sauter (University of Leipzig), I.H. Sloan

website at http://www.ima.org.uk/mathematics/confboundary.htm

Organising Committee: Chair - Ivan Graham (Bath), Sia Amini(Salford),

Simon Chandler-Wilde(Brunel), Ke Chen (Liverpool), Paul Martin (Manchester).

Boundary integral methods are now an established technique for the solution

of partial differential equations in science and engineering, with

applications in many diverse areas including fluid mechanics, fracture

mechanics, acoustics, electromagnetics, inverse problems and free-

and moving-boundary problems.

This meeting will provide a forum for the exchange of ideas between

academic and industrial researchers in different disciplines whose common

interest is boundary integral methods.

As well as discussing recent developments in the theory and numerical

analysis of boundary integral equations, the conference will strive to

encompass applications of contemporary relevance such as direct and inverse

(medium and high frequency) scattering, electromagnetics and moving

boundary problems in hydrodynamics. Continuing progress in key

computational techniques such as multipole, wavelets and panel

clustering, together with innovative algorithm design will be an

additional theme.
