Subject: Donald Kershaw (1928-2016)

I am sad to convey news of the death of Donald Kershaw (Reader
Emeritus at the University of Lancaster, UK) on December 21st 2016 at
the age of 88 following a brief stay in hospital. He had not been well
for some time and suffered from chronic obstructive pulmonary disease.

Following school at Wheelwright Grammar School in Dewsbury (its alumni
also included Leslie Fox and Tom Kilburn), Donald obtained his first
degree at University College Hull, an outpost of London University,
and his PhD from the University of Edinburgh. His scientific work
included computer coding, QD algorithms, linear algebra, special
function theory, approximation theory, quadrature, and integral
equations and their applications.

A detailed account of Donald's career would incorporate his
contributions in the histories of the Admiralty Research Laboratory
(Teddington), of the Computer Unit at Edinburgh University, in
Scottish Numerical Analysis (including the history of the Dundee NA
meetings) and of numerical analysis and approximation at Lancaster
University as well as meetings held at the Mathematisches
Forschungsinstitut Oberwolfach, the London Mathematical Society Durham
Symposia, and SERC conferences at Lancaster University - these stories
liberally sprinkled with the names of many of the contemporary
pioneers in the mathematical sciences and Donald's "mathematical
descendants'. He loved Italy, enjoying visits to Turin and teaching
summer schools at Perugia.

A singularly able yet modest and unassuming mathematician, Donald was
a steadfast friend and will be sadly missed. His hobbies had included
campanology and woodwork and he had a great love of music. He is
survived by his wife Carol, his sons Samuel and Edward, and
grandchildren Rebecca, Thomas, James and Harry.

Subject: MOOC on linear algebra (LAFF) offered again

This spring, "Linear Algebra: Foundations to Frontiers" (LAFF) will
again be offered on edX ( as a semester-long course starting
January 25. LAFF is an introductory course on linear algebra that
links abstractions in mathematics to abstractions in code. The course
targets many audiences, ranging from novices to those wanting a
refresher. The course heavily stresses partitioning of matrices and
vectors and uses our "FLAME notation" to present algorithms.

Later this Spring, we will offer a related course "LAFF-On Programming
for Correctness" (LAFF-On) that builds upon the FLAME notation to
demonstrate how programs can be systematically derived to be correct.
More details on this new course will be given in a future posting to
NA Digest.

To register for LAFF, visit and search for "LAFF".

Subject: Lattice Boltzmann Methods with OpenLB Software Lab, Tunisia, Mar 2017

Registration is prolonged for the spring school Lattice Boltzmann
Methods with OpenLB Software Lab that will be held in Hammamet,
Tunisia, from 6. to 10. March 2017. The spring school introduces
scientists and applicants from industry to the theory of LBM and
trains them on practical problems. The first three days are dedicated
to the theoretical fundamentals of LBM up to ongoing research on
selected topics. Followed by two days of mentored training on case
studies using OpenLB, the participants gain deep inside into LBM and
its applications. This educational concept is probably unique in the
LBM community and offers a comprehensive and personal guided approach
to LBM. Participants also benefit from the knowledge exchange during
poster session, coffee breaks and the excursion at the Mediterranean
sea. We look forward to your participation.

19th IACM International Conference on Finite Elements in Flow Problems
- FEF 2017 - April 5 - 7, 2017 / Rome, Italy.

The Finite Elements in Flow (FEF) Problems Conference has a rich
history that closely parallels the development and maturation of the
finite element method and its application to computational fluid
dynamics problems. The FEF meetings began in Swansea (U.K.) in 1972
and are the principal forum for the exchange of research results in
all aspects of flow simulation using the finite element method. The
scope of the conference is intentionally broad with coverage of
theory, implementation, assessment and application in all of the major
and emerging areas of fluid dynamics and flow-related phenomena.
Deadline for presenting a one page abstract is January 9, 2016 For

Post-doc position, IFP Energies Nouvelles
Rueil-Malmaison - 92500, France

A posteriori error control and adaptivity for flow in porous media
containing faults

IFPEN is pleased to offer a one year postdoctoral position (ideally
starting in April 2017), with a possibility of prolongation up to 1,5
years, related to flow in porous media containing faults. The
candidate will be member of the Applied Mathematics Department of IFP
New Energies at Rueil-Malmaison (France). In particular, the focus of
this position will be on the study of a posteriori error estimation
for flow in porous media containing faults to assess the overall error
of a numerical simulation, identify its different components, and
develop and analyze fully adaptive strategies. The work will be in
collaboration with the project-team SERENA (ex POMDAPI) of INRIA
(Martin Vohralik).

The missions of the successful candidate will be:
- To study the model of flow in porous media containing faults
described by systems of unsteady nonlinear (degenerate) partial
differential equations.
- To undertake theoretical a posteriori error analysis dealing with
the supplement difficulty due to the presence of the faults.
- To use the theory of a posteriori error estimation to assess the
overall error of a numerical simulation, identify its different
components, and develop and analyze fully adaptive strategies.
- To perform implementation into an academic scientific calculation
- To address practical applications to current geoscience problems
like reservoir simulations or the simulation of sedimentary basins.

To apply, send CV highlighting your background in numerical analysis,
scientific computing, and programming, a list of peer-reviewed papers,
a very brief motivation letter, and recommendation letter(s) to
