Subject: Alistair Watson (1942 - 2019)


I regret to announce the death of Alistair Watson, Emeritus Professor
of Numerical Analysis at the University of Dundee. After gaining a
first class degree in Mathematical Sciences from the University of
Edinburgh in 1964 and a PhD from Australian National University under
the supervision of Mike Osborne, Alistair moved to Dundee in 1969,
first on a Fellowship and then as a Lecturer. He made substantial
contributions to Numerical Analysis throughout his career. He took
over the organisation of the Dundee Biennial Numerical Analysis
Conferences from John Morris in 1977 and we shared the duties from
1985 to 2007.

Alistair published extensively, including a text book on Approximation
Theory and another on matrix eigenvalue problems. With his relaxed
style and gentle sense of humour he was much in demand as a conference
and seminar speaker. As well as being co-editor of the IMA Journal of
Numerical Analysis from 1989 to 2004 he was an Associate Editor for
many other journals. He was elected a Fellow of the Royal Society of
Edinburgh in 1996. He also served two periods as head of the
Mathematics Division, a role he carried out with great calmness and
vision. He will be sorely missed by all his friends and former
colleagues.

Alistair was diagnosed with asbestos-related lung cancer in the Spring
of this year. Until his last few days he was cared for at home by his
wife, Hilary, and daughter, Kirsty.

Subject: Dirk Laurie (1946-2019)


Dirk Pieter Laurie (1946-2019)

It is with great sadness that we report that Dirk Laurie passed away
on August 10, after struggling with his health the past six months or
so. A student of AR (Ron) Mitchell, Dirk graduated with a Ph.D. from
the University of Dundee in 1977. He was a researcher at the National
Research Institute for Mathematical Sciences in South Africa, and held
chairs at the Potchefstroom University for Christian Higher Education
(these days Northwest University), as well as Stellenbosch University.
Dirk made significant contributions to a number of areas in numerical
analysis, including quadrature and linear algebra. He was one of five
solo- winners of the SIAM 100-digit challenge of 2002 and a co-author
of the related bestselling book. One of his passions was the South
African Mathematics Olympiad, and he accompanied the national team on
several occasions to the IMO.

Outside of mathematics, his interests were numerous: Chess (South
African schools champion), music (choir singing, playing the recorder,
and general aficionado), cryptic crosswords (both their compilation
and their physical outlay by the LaTeX package he created), and puzzle
solving in general. In his younger days, he was a familiar face on
South African television, where he participated in general knowledge
quiz shows and also served as a pundit during elections. Up to his
death, Dirk was editor- in-chief (and founding member) of the first
online journal for scientific research papers published in Afrikaans,
a language he was passionate about.

Dirk is survived by his wife, Trienke, and five sons.

Subject: Pre-proposals for hosting SIAM Computational Science & Engineering, 2023


The officers of the SIAM Activity Group on Computational Science &
Engineering seek pre-proposals to host CSE23, SIAM's Conference on
Computational Science & Engineering, which is expected to occur in
February or March of 2023.

At this time, we are seeking pre-proposals for host locations outside
of the United States.

CSE is a biennial meeting that has become SIAM's largest meeting, with
roughly 2,000 attendees expected for CSE21. Details on previous CSE
meetings can be found at the SIAG/CSE's wiki at
http://wiki.siam.org/siag-cse .

Hosting CSE23 provides a vital service to the international
computational science & engineering and SIAM communities. Most recent
and upcoming SIAM conferences held outside of the US and Canada have
involved a local institution taking financial responsibility, with
SIAM providing various program management and marketing services for a
fee. In addition to this model, SIAM welcomes pre-proposals from
institutions interested in alternative models, including those where
SIAM takes full financial responsibility and those where SIAM and a
local institution share the risk and revenue.

Pre-proposals will be examined by the SIAG/CSE officers and SIAM, who
will then issue invitations for detailed proposals. The final decision
is expected to be made in the January 2020 time period.

Further information and requested preproposal content can be obtained
from the SIAG/CSE officers and SIAM's Director of Programs and
Services, Richard O. Moore .

Pre-proposals are due by October 1, 2019 (no extensions) to the
SIAG/CSE program director at wild@mcs.anl.gov .

Subject: Research Scientist Position, Modeling and analysis of ecosystems


The Laboratoire de Mathématiques de l’INSA Rouen Normandie (LMI –
EA3226, FR CNRS 3335) offers a position of research scientist (ingénieur
de recherche) for the project ECUME. This project involving several
biology laboratories, aims at studying the impact on oyster culture of fields
of wind turbines. We study graph models for ecosystems.
First, we will study static models corresponding to flow models in graphs
typically studied in operations research. The problem is orignal because
these flows (CO2 exchanges) are difficult to measure in situ; we would like
to estimate the values carried by the edges of the graph following different
criteria, study the polyhedron of feasible solutions and identify an objective
function (which is not known). In a second phase we will consider
dynamical models, i.e. ordinary differential equations involving the graph
Laplacian.
Computations will first be done on a local LMI server and then on the
servers of the CRIANN computing center of Normandie.

Keywords: graphs, flows, polyhedra, optimisation, modelling, dynamical
systems.

Duration : 8 to 12 months with possible renewal starting in the fall of 2019
Salary : about 2200€/month

Background of the candidate :
We expect a solid training in applied mathematics, computer science or
operations research (good level M5/ engineering degree or doctorate). The
research scientist will have the opportunity to participate in the
development of models with the team of researchers. He will implement
these models on a work station dedicated to the project. He should have
one or several experiences of code development for scientific computing.
Know-how in parallel computing would be a plus. Finally, we will
encourage the research scientist to present the results in scientific
conferences and co-author research articles.

Subject: CFP, J Nonsmooth Analysis and Optimization, Inaugural Issue


The Journal of Nonsmooth Analysis and Optimization
(https://jnsao.episciences.org) is calling for papers for its
inaugural volume. This newly established scholarly journal, provided
on a Fair Open Access basis - without cost to both readers and
authors, see below - disseminates peer-reviewed articles in all
aspects of nonsmooth analysis relevant to optimization and equilibrium
problems such as (but not limited to) analysis of infinite-dimensional
algorithms for nonsmooth optimization and equilibrium problems, in
particular in function spaces, necessary and sufficient optimality
conditions based on generalized derivatives, sensitivity and stability
properties - including regularization theory - of nonsmooth
optimization and equilibrium problems, solution properties such as
preservation of continuity or discontinuity properties of problem
data, problem reformulations such as convex relaxation and lifting,
optimization of variational inequalities and nonsmooth equations, bi-
and multilevel optimization, robust and chance-constrained
optimization.

Papers focusing on applications (e.g., optimization in data science or
energy markets) are also welcome if the results are of broader
interest beyond application specialists and contain mathematical
insights (either analytical or algorithmic) that are relevant for
other applications as well. The journal also expressly invites works
of an expository nature.

The full list of editorial board members can be found under
https://jnsao.episciences.org/page/editors

As a Fair Open Access journal, it is owned and controlled by the
scholarly community independent of commercial publishers, authors
retain copyright of their works, which are published under a standard
