Subject: New Book, Monotone Discretizations for Elliptic Second Order PDEs

Monotone Discretizations for Elliptic Second Order Partial
Differential Equations
by Gabriel R. Barrenechea, Volker John, and Petr Knobloch

This monograph contains the first comprehensive presentation of
monotone discretizations for elliptic boundary value problems. The
emphasis is on finite element methods, but finite volume and finite
difference methods are also included. A general framework for the
proofs of monotonicity and discrete maximum principles is developed
for both linear and nonlinear discretizations. This framework allows
for the analysis to be carried out in a unified way for most of the
available methods. In addition to the monotonicity, for all methods
for which error and solvability analyses are available, these are
presented in detail. Besides the unified presentation of the material
already published in the literature, various new results are also
presented. Extensive numerical comparisons between different methods
complement the theoretical considerations.

Subject: Workshop Talca Numérica, Chile, Jul 2025

Dear colleagues,

We are organizing the 10th version of the Numerical Cities series of
workshops in Chile. This one is Talca Numérica, to be held on July 2-4
2025, at the Universidad Católica del Maule, Talca, Chile. There will
be no registration fee and the participation includes coffee breaks
and a conference dinner, but registration is mandatory.

This 3-day event considers a unique session with 2 daily plenary
lectures, and its main topic will be Numerical Analysis of PDEs. We
expect to have about 60 national and international participants.

More details about the event can be found in its website:
https://www.ci2ma.udec.cl/TN/,
and should you have further questions, please do not hesitate to
contact me.

Best Regards,
Nicolás Barnafi, in representation of the Organization Committee

Subject: Call for contributions: preCICE Workshop, Hamburg, Sep 2025

preCICE is an open-source coupling library for partitioned
multi-physics and multi-scale simulations. It enables the efficient,
robust, and parallel coupling of separate single-physics
solvers. preCICE treats these solvers as black-boxes and, thus, only
minimally-invasive changes are necessary to prepare a solver for
coupling. Ready-to-use adapters for well known open-source solvers,
including OpenFOAM, SU2, CalculiX, FEniCS, and deal.II, are
available. The software offers methods for equation coupling, fully
parallel communication, data mapping, and time interpolation.

The preCICE Workshop 2025 will take place at HSU Hamburg on 8th to
12th of September. The workshop will include an introduction course
and is, thus, suitable for new and experienced users. We will extend
the course by a new module on HPC. Afterwards, the maintainer team
will present recent updates on dynamic meshes, mesh-particle coupling,
and macro-micro coupling – to only mention a few highlights. And we
will continue the standardization process of adapters and application
cases, where you can help shaping the future.

We are looking for talks and posters that could be beneficial for the
wider preCICE community. Are you developing a new adapter (such as for
G+Smo or ISSM last year)? Are you using preCICE for an exciting new
application? Are you developing new methods that should not be missing
from preCICE? If the answer to any of these questions was yes, we
encourage you to submit a brief abstract for a 20 minutes talk. Are
you revisiting one of the classical preCICE use cases? Did you already
present your work in a previous workshop? Then we would be very happy
to catch up with your work and we encourage you to present a
poster. You do not need to submit a contribution to join this
workshop. However, your contributions are very welcome!

Submission deadline: 31st of May.

Subject: PhD Position in Applied Mathematics, University of Duisburg-Essen, Germany

The University Duisburg-Essen is seeking at the Campus Essen in the
Faculty of Mathematics, in the working group Infinite-dimensional
Optimization, headed by Prof. Antoine Laurain, a Scientific Researcher
(Salary Classification 13 TV-L, 75 %).

The PhD student will participate in the AEI-DFG research project
FLEXION: "Design of FLEXible materials and structures via shape and
topology optimizatION." The goal of this project is to advance the
mathematical analysis of shape and topology optimization for materials
described by nearly incompressible and incompressible hyperelasticity,
applying these techniques for the design of flexible materials and
structures, with a specific focus on utilizing shape and topological
derivatives. This AEI-DFG joint initiative brings together the
expertise of specialists in shape/topology optimization and material
design from Spain and Germany. The two teams will collaborate closely
throughout the duration of the project. The Spanish team is based at
CIMNE in Barcelona.

Your profile: A completed university degree in mathematics with a
minimum standard study period of 8 semesters. Academic knowledge in at
least two of the following areas: partial differential equations,
numerical mathematics, optimal control, optimization, calculus of
variations. Experience in numerical programming with Python, C/C++,
Matlab, or similar environments.

Instructions for application can be found at:
https://www.uni-due.de/karriere/stelle.php?kennziffer=164-25

precision, hierarchical matrices, ...) as well tools for theoretical
analysis (e.g., Fourier analysis, continued fractions, ...) depending
on their primary interest, all within the framework of domain
decomposition methods and their analysis. Applications are invited
from candidates who have background in numerical linear algebra,
numerical analysis, domain decomposition methods, or
computational/data science application domains. The anticipated start
is in fall 2025 but is negotiable. Successful candidates must hold a
