Subject: Ludwig Elsner, Jan 17, 1939 – Feb 25, 2023

With deep sadness we announce that Ludwig Elsner passed away. He died
on February 25, 2023 in Halle (Westfalia), Germany, at the age of
84. Ludwig, professor emeritus of mathematics at the University of
Bielefeld, has been well-known for his excellent work in linear and
multi-linear algebra, in numerical linear algebra, and in particular
for his inclusion theorems for eigenvalues with their concise and
elegant proofs.

His family, his many friends, colleagues and students all remember him
as an attentive, kind, calm, caring, competent and appreciative
person. A more extensive obituary will be posted soon.

Subject: Share your advisee-advisor experiences

Katie Kavanagh and I are writing a book for applied mathematics
graduate students and faculty about the graduate advisor-advisee
relationship. The book gives an overview of the PhD process with an
emphasis on the importance of effective mentorship and a clear
understanding of the roles and responsibilities of both the student
and the advisor.

To this end, we are looking for vignettes to include in the book that
illustrate the numerous issues, challenges, rewards, and outcomes
arising throughout the various stages of the PhD process in the
context of advising. We are well aware that not all stories are
positive and in fact, understand that there is much to be learned from
sharing the more negative experiences. We would like to gather a set
of experiences that covers a wide range of possible scenarios.

Our hope is that by shedding light on some of the challenges that
arise, both students and new faculty can be better prepared for the
entire process.

Please use the online form at
to help us.

Any information collected will be made anonymous and we may edit the
responses for length and clarity.

Subject: New Book, Computational Optimization: Success in Practice

CRC Press (Taylor & Francis) has recently published Computational
Optimization: Success in Practice

This textbook is designed for graduate students of math, computer
science, engineering, and all who explore optimization techniques at
different levels for educational or research purposes. It might also
benefit many professionals in academic and industry-related research
as it offers a guided tutorial reviewing the theoretical fundamentals
while going through the practical examples used for constructing a
computational framework applicable to various real-life models. This
framework will be assembled piece by piece; the readers may apply this
process at the levels of complexity matching their current projects or
research needs.

Features: The main optimization framework builds through the course
exercises and centers on MATLAB.  All other scripts to implement
computations for solving optimization problems with various models use
only open-source software.  Each chapter contains problems based on
the examples provided in the text and associated scripts. The readers
will not need to create the scripts from scratch but rather modify the
codes provided as a supplement to the book
(  This book has
everything to teach computational optimization: theory review,
practical examples, homework problems, computer lab assignments, and
lecture slides available to instructors by request

Subject: ECM Networking, BAMC 2023, Apr 2023

Design West, 16 Narrow Quay, Bristol, BS1 4QA, UK

Welcome to the icebreaker event for Early Career Mathematicians (ECM)
at the BAMC 2023, sponsored by the ECM Committee of the Institute of
Mathematics and its Applications (IMA). We had a fantastic time last
year at Loughborough, so much so that we are going to run the same
event in Bristol. We are hosting the event at Design West, right in
the city centre of Bristol, the evening before the BAMC begins.

Feedback we, the Committee, received from our members is that
networking and forming contacts with others at conferences can be
daunting. In the instances that a group of friends has been formed,
they have said that the enjoyability of the conference improves
significantly. So, forming contacts and groups is what we want to
facilitate at this event. We will start the event with quick opening
speeches about the BAMC (and ECMs) from one of the Organising
Committee and who the ECM Committee are and what they do for the
IMA. Then we will start the activities, which include:
- Knowing me, knowing you
- Mathematical Taboo
- Celebrity Cameo
- Mathematical Headbandz
- Shakespeare's Radio

Refreshments will be supplied and you are welcome to join the ECM
Committee for an informal dinner after the event.

student or post-doctoral researcher, m/f/d) in the fields of damage
detection in fiber metal laminates using physics informed neural
networks (PINNs) and methods from data assimilation (full-time , 100 %
- temporary).

The position is initially limited for a period of 3 years. It is
intended to serve the qualification of young scientists and offers the
opportunity for a doctorate or for further scientific qualification.
The scientific activity takes place within the framework of the DFG-
funded research group FOR 3022 "Ultrasonic monitoring of fiber metal
laminates using integrated sensors" in subproject 4 "Automated data-
driven damage detection". With the help of guided ultrasonic waves in
fiber metal laminates, damage within the material is to be detected
and, if necessary, even characterized. For this purpose, mathematical
models (differential equations) as well as (synthetic and
experimental) measurement data are used. In work group Lorenz, machine
learning methods (in particular Physics Informed Neural Networks) will
be used, adapted, analyzed and further developed for this purpose. In
the work group Grassle the focus is on the application, further
development and implementation (theory and numerics) of methods of
data assimilation using model reduction techniques for the detection
of damages in fiber metal laminates. The work group Lorenz moves to
the University of Bremen during the project period - if desired, the
activity can also be taken up directly there.

Subject: CFP, Symmetry, Special Issue, Topological Dynamical Systems

In recent decades, the topological theory of dynamical systems has
rapidly developed. In particular, topological dynamical systems are
nowadays widely applied in chaos theory, combinatorics, fractal
geometry, etc. The theory of topological dynamical systems is one of
the most interesting research fields in contemporary mathematics. Many
of its theoretical results have found many real-world applications.
In the last twenty years, considerable attention has been paid to the
theory's connections with fractal sets and function spaces, especially
towards links with wavelet analysis. Therefore, topological dynamical
systems act as links between several mathematical fields, and in
general between different fields of the functional analysis. In
particular, topological dynamical systems deal with the topological
properties of dynamical systems, i.e., the study of phenomena related
to iterations of continuous maps defined on topological spaces. The
topological approach to dynamical systems, due to the pioneering work
of Henry Poincare on the topological properties of differential
equations, is relevant both in the qualitative theory of dynamical
systems and in the numerical theory of dynamical systems. More
importantly, dynamical systems may often possess different kinds of
symmetry. Both continuous dynamical systems and discrete dynamical
systems exhibit, in different ways, a local form of symmetry at
minimum (e.g., Henon map, Lorenz attractor). In fact, in order to
understand the models that describe the world around us, we need to
know the best way to model the symmetry of nature.  In this Special
Issue, we invite and welcome review, expository, and original papers
dealing with recent advances in the modern theory of topological
dynamical systems, and, from a more general point of view, all
theoretical and practical studies in pure and applied mathematics
focused on this topic.

The main topics of this Special Issue include (but are not limited
to): Dynamical systems for fixed point problems and variational
inequalities; Operators, dynamical systems and global convergence in
measurable function spaces; Continuous dynamical systems and integral
equations; Discrete dynamical systems, iterative process and limit
sets; General theory of dynamical systems; Orbits, attractors and
iterated function systems; Chaos theory, combinatorics and fractal
sets; Isomorphism of dynamical systems and integral transformations;
Random dynamical systems and applications.

2022 and which served as a central kick-off event of the merger of the
two previous conference series "Model Reduction of Parametrized
Systems (MoRePaS)" and "Model Reduction of Complex Dynamical Systems
(Modred)". The collection addresses recent results and significant new
achievements in model reduction and surrogate modeling. It is not
restricted to papers by authors who attended the MORe conference.

The submission deadline is April 30, 2023. More details on the scope
of the topical collection and further information can be found under
the following link:
