Professor Christopher TH Baker 1939-2017
BA (1961) MA DPhil (1964) FIMA (1979) DSc (Honoris Causa)

We are sorry to convey news of the passing of Christopher Baker a well
known member of the international Numerical Analysis community with
research interests in mathematical and computational modelling, the
analysis and numerical analysis of functional differential equations
and evolutionary problems with after-effect (including
integro-differential equations and deterministic and stochastic
delay-differential equations). He will be remembered by many for four
books devoted to the numerical solution of integral equations, for
well over 100 journal articles, and by his many PhD students for his
enthusiasm, his determination to enable his students to succeed, and
his willingness to spend as much time as it takes to ensure junior
colleagues are able to make progress in their research and become

Born in 1939, Christopher Baker was educated at Colchester Royal
Grammar School, and Jesus College, Oxford. He gained his BA in 1961
and his MA and DPhil in Mathematics in 1964. Following two years as a
member of faculty of the University of California at Berkeley, he
moved to the University of Manchester where he served successively as
lecturer, senior lecturer, reader and professor.

In 2004, following his time as research professor at the University of
Manchester (where he had served as Founding Director of the Manchester
Centre for Computational Mathematics and, for 3 years, as Head of the
Mathematics Department), Christopher joined the University of Chester
as a part-time member of the department, retiring from that role in
2016. At the time of his death he held the title of Emeritus Professor
at both the University of Manchester and the University of Chester.
Christopher is survived by his wife Helen, his children Deborah and
Mark, and four grandchildren.

Subject: Fast Algorithms for Maxwell's Equations (FAME)

Fast Algorithms for Maxwell's Equations (FAME) is a package for
solving three-dimensional source-free Maxwell's equations with all
fourteen Bravais periodical lattice structures. The package is now
available from the website: .

FAME is equipped with theoretical and numerical proofed algorithms
such as singular value decomposition of discrete single and double
curls, fast FFT-based matrix-vector multiplications, and null-space
free eigensolver. Both MATLAB and GPU versions of FAME are available
for maximum usability and efficiency, respectively. FAME has been used
to simulate various materials, compute band structures, design crystal
structures, and simulate electromagnetic fields.

Subject: SuiteSparse:GraphBLAS released

I would like to announce the release of SuiteSparse:GraphBLAS version
0.2.0, available at .

SuiteSparse:GraphBLAS is a nearly full implementation of the GraphBLAS
standard, which defines a set of sparse matrix operations on an
extended algebra of semirings using an almost unlimited variety of
operators and types. When applied to sparse adjacency matrices, these
algebraic operations are equivalent to computations on graphs.
GraphBLAS provides a powerful and expressive framework for creating
graph algorithms based on the elegant mathematics of sparse matrix
operations on a semiring. More details on the GraphBLAS standard are
available at .

Performance of SuiteSparse:GraphBLAS is either on par with the
corresponding operations in MATLAB, or faster. Submatrix assignment
is particularly efficient. In one example, C(I,J)=A for a matrix C of
size 3 million-by- 3 million with 14 million nonzeros, and a matrix A
of size 5500- by-7000 with 38500 nonzeros, takes 82 seconds in MATLAB
but only 0.74 seconds in SuiteSparse:GraphBLAS. This result includes
finalizing the computation and returning the result to MATLAB as a
valid sparse matrix. SuiteSparse:GraphBLAS also includes a
non-blocking mode, so that a sequence of submatrix assignments can be
still more efficient.

SuiteSparse:GraphBLAS is at version 0.2.0, but the code is highly
polished, well-documented, and fully tested. It's as robust as any of
my other packages in SuiteSparse. However, the GraphBLAS
specification is still provisional, and there are a few minor
variations between the SuiteSparse:GraphBLAS implementation and the
specification. Once these are resolved, SuiteSparse:GraphBLAS version
1.0 will be released.

Subject: PaMPA Day, France, Oct 2017

The "PaMPA day" workshop will take place the 18th of October at Inria
Bordeaux - Sud-Ouest. You are warmly invited to attend/contribute to
the first "PaMPA Day". This day is dedicated to feedback regarding the
PaMPA software, on the features of parallel handling of distributed
meshes and parallelization of remeshing. In particular, some results
on the coupling of PaMPA with the sequential remeshers Mmg3d, Tetgen
and Gmsh will be presented.

PaMPA ( is designed using a modular
architecture : the foundation library for distributed mesh handling
("PaMPA-Core") is available through free download under a free/libre
software license, and the parallel remeshing module ("PaMPA-Remesh")
is at the time being available on demand, under a privative/non-free
license. PaMPA is currently used by one big industrial company to
build, through refinement, very large meshes (above 1 billion
elements) in reduced time.

There is no registration fee and only the registered persons will be
allowed to participate to the "PaMPA day". A registration form is

Subject: Postdoc Position, Mean Field Games, Inria Saclay and CMAP

The Inria-Saclay center offers a (renewable) one year postdoc position
in the Commands team of the Applied Math Center of Ecole Polytechnique
(CMAP): . The research theme will be
MFG with application to electricity production.

The MFG approach allows to modelize the way the crowd can influence
the personal behavior. This is particularly relevant for the analysis
of changes in the economic behavior (as for critical levels for the
adoption of new technologies). The models, based on stochastic
control, boil down to resolve coupled parabolic equations by finite
differences or semi lagrangian schemes. The main themes will be
- Analysis of existence of an equilibrium
- Choice of discretisation and numerical analysis (convergence order)
- Choice of optimization algorithms allowing to solve the discrete

Subject: PhD Positions, ICES/Aerospace, UT Austin

Two PhD students are immediately available in Prof. Bui's
Computational Engineering and Optimization Group at the Institute for
Computational Engineering and Sciences, and the Department of
Aerospace Engineering. Below are the detailed description for each of
the position.

#1 PhD position: The student will have the opportunity to work on the
development of reduced-order methods (aka model reduction methods) for
large-scale Neutron transport equation. The idea behind reduced-order
methods (ROMs) in this project is to reduce the cost of solving
large-scale Neutron transport equation discretized by the
Discontinuous Galerkin method. The student is responsible for
developing mathematical ROM algorithms, coupled with physics-based
ROMs, to produce real-time simulation of Neutron transport equation to
study nuclear weapon radiation effects. The project is in
collaboration with Texas A&M.

#2 PhD/postdoc position: The student will have a chance to work in a
multi-lab and multi-university 15M project on Fusion energy supported
by the Department of Energy. The whole project aims at Tokamak
Disruption Simulations. UT is responsible for developing parallel
high-order hybridized discontinuous Galerkin (HDG) methods for
magnetohydrodynamics system (coupled Navier-Stokes and Maxwell
equations) for multiphysics plasma simulations.

Requirements: potential candidates are those who have been working on
discretization of PDEs, are interested in mathematics, and strong in
programming. Strong background in computational mathematics is a plus.

Please contact Dr. Bui at for more details if
you are interested in either of these two positions.
