Subject: Ben Sommeijer 1949-2009

We are sad to inform you of the death of Dr. B.P. Sommeijer of the
Centrum Wiskunde & Informatica (CWI), Amsterdam, on November 19, 2009.
He was diagnosed with cancer in early 2009.

Ben Sommeijer was born in Alkmaar, the Netherlands, on November 4,
1949. He studied mathematics and scientific computing at the
Technical University of Eindhoven and the University of Amsterdam from
1967-1977 and earned a Ph.D. from the University of Amsterdam in 1992.
He was active in the field of numerical analysis of ordinary and
partial differential equations at CWI in Amsterdam, where he was
employed from 1976 until his death. His contributions included the
Runge-Kutta-Chebychev methods for explicit and semi-implicit solution
of stiff differential equations, as well as highly successful applied
work on the dynamics of phytoplankton.

Ben was co-organizer of the NUMDIFF conferences in Halle, Germany, and
editor of the conference proceedings since 2000. He was also Senior
Editor of the Journal of Computational and Applied Mathematics.

Condolences to the family may be addressed to: Mrs. Leny Sommeijer,
Laan van Muijs 3, 1852RD Heiloo, The Netherlands. E-mail:

Subject: Long time computability of the Lorenz system

I have a student working on solving the Lorenz system on long time intervals
using high order methods (ca 200) and high precision (ca 400 digits). Does
anyone know about any reference solutions to the Lorenz system over long time
intervals? The longest time intervals I've seen are T = 30 (by Estep and
Johnson in M3AS 1998) and T = 50 (incidentally by Logg in SISC 2003). Does
anyone know of any other results claiming computability over longer time
intervals? I know of some shadowing results over long intervals, but that's
not what I'm after.

Subject: New book, The birth of numerical analysis

It is our pleasure to announce the publication of the book:
The Birth of Numerical Analysis
Eds. Adhemar Bultheel & Ronald Cools
ISBN: 978-981-283-625-0 / World Scientific

The 1947 paper by John von Neumann and Herman Goldstine, "Numerical
Inverting of Matrices of High Order" (Bulletin of the AMS, November 1947),
is considered as the birth certificate of numerical analysis. Since its
publication, the evolution of this domain has been enormous. This book is
a unique collection of contributions by researchers who have lived through
this evolution, testifying about their personal experiences and sketching
the evolution of their respective subdomains since the early years.

The Institute for Mathematics and its Applications (IMA) at the University of
Minnesota announces membership opportunities in connection with its 2010-2011
thematic program

Simulating our Complex World: Modeling, Computation and Analysis

This subject involves many interesting challenges in computational science and
engineering. Individuals may apply for four classes of membership:

* IMA Postdoctoral Fellowships
* IMA Industrial Postdoctoral Fellowships
* IMA General Memberships
* IMA New Directions Research Professorships

IMA POSTDOCTORAL FELLOWSHIPS provide an excellent opportunity for mathematical
scientists near the beginning of their career who have a background in and/or
an interest in scientific computing, numerical solution of differential
equations, inverse problems, and optimization. IMA postdoctoral fellowships
run one to two years, at the option of the holder,
starting September 1, 2010. In the second year of the appointment there are a
variety of options to enhance career development, including participation in
the 2011-2012 academic year program, teaching, and working on an industrial
project. (application deadline January 4, 2010)

IMA INDUSTRIAL POSTDOCTORAL FELLOWSHIPS are designed to prepare mathematicians
for research careers in industry or involving industrial interaction. IMA
industrial postdoctoral fellowships run two years starting September 1, 2010.
They are funded jointly by the IMA and an industrial sponsor, and holders
devote 50% effort to their own research and the IMA program and 50% effort
working with industrial scientists. (application deadline January 4, 2008)

IMA GENERAL MEMBERSHIPS provide an opportunity for mathematicians and
scientists employed elsewhere to spend a period of one month to one year in
residence at the IMA, and to participate in the 2010-2011 thematic program.
The residency should fall in the period September 2010 through June 2011.
Logistic support such as office space, computer facilities,and secretarial
support will be provided, and local expenses may be provided. The research
interests of General Members must relate to the thematic program and a
doctoral degree is normally expected. Applications may be submitted at any
time until the end of the thematic program, and will be considered as long as
funds remain available. (applications considered immediately and until funds
are exhausted)

opportunity for established mathematicians -- typically mid-career faculty at
US universities -- to branch into new directions and increase the impact of
their research and teaching by spending the 2010-2011 academic year immersed
in the thematic program at the IMA. Visiting Professors will enjoy an
excellent research environment and stimulating scientific program. New
Directions Research Professors are expected to be resident and active
participants in the program but are not assigned formal duties. The New
Directions program will supply 50% of academic year salary up to $50,000
maximum. A semester long visit is also possible. (application deadline January
4, 2010)

All IMA members are provided with an excellent and extremely stimulating
research environment and connection with a large community of first class
researchers. The IMA is a national institute whose mission is to increase the
impact of mathematics by fostering research of a truly interdisciplinary
nature, linking mathematics of the highest and important scientific and
technological problems from other disciplines and industry. Allied with this
mission, the IMA also aims to expand and strengthen the talent base engaged in
mathematical research applied to or relevant to such problems. It was founded
in 1982 and receives its primary funding from the National Science Foundation.

Application forms and instructions are available at .
