Subject: New Book, Numerical Methods for Elliptic and Parabolic PDEs

Numerical Methods for Elliptic and Parabolic Partial Differential Equations
by Peter Knabner and Lutz Angermann
with contributions by Andreas Rupp
Texts in Applied Mathematics, vol. 44

This graduate-level text provides an application oriented introduction
to the numerical methods for elliptic and parabolic partial
differential equations. It covers finite difference, finite element,
and finite volume methods, interweaving theory and applications
throughout. The book examines modern topics such as adaptive methods,
multilevel methods, and methods for convection-dominated problems and
includes detailed illustrations and extensive exercises. For students
with mathematics major it is an excellent introduction to the theory
and methods, guiding them in the selection of methods and helping them
to understand and pursue finite element programming. For engineering
and physics students it provides a general framework for the
formulation and analysis of methods.

This second edition sees additional chapters on mixed discretization
and on generalizing and unifying known approaches; broader
applications on systems of diffusion, convection and reaction;
enhanced chapters on node-centered finite volume methods and methods
of convection-dominated problems, specifically treating the
now-popular cell-centered finite volume method; and the consideration
of realistic formulations beyond the Poisson's equation for all models
and methods.

Subject: Parallel and Distributed Sci and Eng Computing, France, May 2022

The 23nd IEEE International Workshop on Parallel and Distributed
Scientific and Engineering Computing (PDSEC-22) ( will be held on May 30, 2022 in Lyon, France in
conjunction with IPDPS 2022.

Deadline: PDSEC-22 deadline: 21 Jan 2022 (AoE)

Scope and Interests: The technological trends in HPC system evolution
indicates an increasing burden placed on application developers due to
the management of the unprecedented complexity levels of hardware and
its associated performance characteristics. Many existing scientific
applications codes are unlikely to perform well on future systems
without major modifications or even complete rewrites. In the future,
it will be necessary to utilize, in concert, many characteristics such
as multiple levels of parallelism, many lightweight cores, complex
memory hierarchies, novel I/O technology, power capping, system-wide
temporal/spatial performance heterogeneity and reliability concerns.
The parallel and distributed computing (PDC) community has developed
new programming models, algorithms, libraries and tools to meet these
challenges to accommodate productive code development and effective
system use. However, the scientific application community still needs
to identify the benefit through practical evaluations. Thus, the
focus of this workshop is on methodologies and experiences used in
scientific and engineering applications and algorithms to achieve
sustainable code development for better productivity, application
performance and reliability.

electromobility, bioeconomy and personalized product design. The PhD
topics deal with the development and application of numerical methods
and their integration to multiscale models using gradient-based
optimization methods, AI-based data analysis methods and/or database

PhD Position: Polynomial Optimization in Structural Engineering

Polynomial optimization is an exciting area of research in
optimization, just at the boundary between what is undecidable
(continuous optimization) and what is efficiently solvable (easier
conic optimization problems, such as linear and semidefinite
programming). Sustained progress in the field over the past two
decades has enabled new applications within many areas of engineering.

There is a PhD studentship available in related topics, to be
supervised by Jakub Marecek and Vyacheslav Kungurtsev (Dept. of
Computer Science) and Didier Henrion (Dept. of Control Engineering) at
the Czech Technical University, in close collaboration with the teams
of Jan Zeman (Department of Mechanics) and Michal Kocvara (School of
Mathematics at the University of Birmingham, UK). The position is full
time and limited to 3 years, but can be extended in case of mutual
interest. The studentship comes with a monthly salary similar to the
average pay in Prague, the Czech Republic (approximately 45000 CZK per
month before a notably low tax), and a travel budget. The Czech
capital regularly ranks among five European cities within the world's
best cities in the world to live in (cf. Time Out Magazine index for
2021) and CTU's offices are in a centrally-located palace with a view
of Prague Castle. For more information, please see

We seek candidates with Masters degrees in Mathematics, Computer
Science, Operations Research, Engineering or related disciplines, with
excellent mathematical aptitude, as demonstrated by involvement in
mathematical olympiads, relevant coursework, or undergraduate
research. A preference is given to: candidates with experience with
semidefinite programming; candidates with experience with structural
engineering; candidates with experience in frequency-domain methods
(e.g. signal processing); candidates with experience in programming in
Python or MATLAB. We expect to start interviewing candidates in
January 2022. Please leave your email address at or contact us via email.
