Subject: Pat Gaffney
From Ronald Cools, chair of IFIP WG 2.5:
Pat Gaffney, a regular member of our Working Group, passed away on
Sunday 13th September in Bergen District, Norway. Below is a CV that
Berit Hilt prepared for her husband.
Patrick W. Gaffney was awarded his M.Sc. in Mathematics from Oxford
University in 1974 and his D.Phil in Mathematics from Oxford
University in 1977.
From October 1975 until July 1977 he was a research assistant at the
United Kingdom Atomic Energy Authority in Harwell from where he moved
to Oak Ridge National Laboratory in USA, Tennessee. Between July 1977
and June 1984 he worked as a Numerical Analyst-Consultant becoming a
Senior Research Staff member of the Computer Sciences Organization.
In September 1984 he moved to Norway to establish a Centre for
Computer Science at the Christian Michelsen Institute in Bergen,
Norway.
In October 1986 he joined IBM as manager of the newly created Bergen
Scientific Centre - now renamed to the IBM Bergen Environmental
Sciences & Solutions Centre. IBM closed the Centre in June 1994. His
research areas are Numerical Software and Approximation. 1994-2016 he
had his own company, BSSI.
He has been editor of the ACM SIGNUM newsletter (1984-1994), and from
1991 he was associate editor of the ACM Transactions on Mathematical
Software. He has been a member of the Society for Industrial and
Applied Mathematics, a Fellow of the Institute of Mathematics and its
Applications (IMA), the IMA representative for Norway, a member of the
International Federation for Information Processing (IFIP) Working
Group 2.5 on Numerical Software, a member of the Ada-Europe Numerics
Working Group, and a Professor II at the Department of Information
Science at the University of Bergen.

Subject: Einstein Field Equations, ONLINE, Oct 2020
We would like to invite you to the second workshop as part of the
semester-long program "Advances in Computational Relativity".
This second workshop will focus on theoretical and computational
approaches to solving the vacuum Einstein field equations (the master
equation of general relativity: a nonlinear, coupled,
hyperbolic-elliptic PDE system) without matter field sources. A
particular important special case is the simulation of two merging
black holes, which will be emphasized throughout the workshop.
Gravitational wave solutions will be another important aspect of this
workshop, and special attention will be given to modeling techniques
for the computation of these waves. Important, recent advances in
mathematical aspects of Einstein's theory of general relativity will
also be a central topic of the workshop.
Please apply using the link "Apply with Cube" at the workshop website
(https://icerm.brown.edu/programs/sp-f20/w2/) if you would like to
participate in this workshop.

From: Dajana Conte [log in to unmask]
Date: September 29, 2020
Subject: Postdoc Position, Structure-preserving Approximation, Univ of Salerno
The Department of Mathematics of the University of Salerno has
published a call for applications for a research grant as part of the
PRIN2017 project "Structure-preserving approximation of evolutionary
problems" (PI: Prof. Raffaele D'Ambrosio, local coordinator:
Prof. Dajana Conte). The deadline for submitting the application is
set for 21 October 2020. The duration of the grant is 12 months. The
notice is available at:
https://web.unisa.it/en/research/research-grants/necessary-requisites?
anno=2020&bando=3790
The application form must be submitted exclusively electronically
through the page https://pica.cineca.it/unisa/unisa2020-adr059/
The research activities will be carried out within the PRIN2017
project "Structure-preserving approximation of evolutionary problems",
which focuses on numerical structure-preserving modeling for numerous
evolution problems in time, in space, with memory, deterministic and
stochastic. The main activity of the research fellow will focus on
the development and analysis of numerical schemes which, in addition
to verifying the usual properties of accuracy, efficiency and
stability, are also capable of retaining important qualitative
properties of the solution of the problem in question, the geometry of
the problem, any non-linear invariants. This investigation will
involve deterministic and stochastic operators, with consequent
repercussions on the peculiarity of the required analysis, as well as
in the development of prototype mathematical software based on the
produced numerical modeling.
