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. A.

Nabben ------------------------------------------------------- From: Tim Kelley [log in to unmask] Date: March 14, 2023 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 https://go.siam.org/advisorsurvey to help us. Any information collected will be made anonymous and we may edit the responses for length and clarity. ------------------------------------------------------- From: Vladislav Bukshtynov [log in to unmask] Date: March 16, 2023 Subject: New Book, Computational Optimization: Success in Practice CRC Press (Taylor & Francis) has recently published Computational Optimization: Success in Practice https://www.routledge.com/Computational-Optimization/Bukshtynov/p/book/9781032229478 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 (http://www.bukshtynov.xyz/book_CompOPT_support.html). 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 (http://www.bukshtynov.xyz/book_CompOPT_instructor.html). ------------------------------------------------------- From: Pamela Bye [log in to unmask] Date: March 17, 2023 Subject: ECM Networking, BAMC 2023, Apr 2023 Design West, 16 Narrow Quay, Bristol, BS1 4QA, UK https://ima.org.uk/21068/ecm-networking-icebreaker-at-the-bamc-2023/ 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. Register here - https://my.ima.org.uk/services.php?section=events If you are attending the conference please use the hashtag #ECMIcebreaker2022 and tag the IMA on socials! ------------------------------------------------------- From: Harbir Antil [log in to unmask] Date: March 14, 2023 Subject: East Coast Optimization Meeting (ECOM), ONLINE, Apr 2023 The schedule of the East Coast Optimization Meeting (ECOM) 2023 is now available: https://math.gmu.edu/~hantil/ECOM/2023/ Our two keynote speakers - Prof. Michael Ferris (University of Wisconsin Madison) - Prof. Uday Shanbhag (Pennsylvania State University) will give two hour tutorials (each) and additional one hour long keynote talks.

Contributions to the special issue are welcome! ------------------------------------------------------- From: amelia sun [log in to unmask] Date: March 14, 2023 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.

The topical collection is an initiative of the first "MORe" conference which was held in September 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: https://www.springer.com/journal/10444/updates/23848990 ------------------------------------------------------- From: Romas Baronas [log in to unmask] Date: March 17, 2023 Subject: Contents, Nonlinear Analysis: Modelling and Control, 28 (2) Nonlinear Analysis: Modelling and Control, ISSN 1392-5113, Volume 28, Number 2, 2023 https://www.journals.vu.lt/nonlinear-analysis TABLE OF CONTENTS Xili Wu, Liangwei Wang, Zhengwen Tu, Yuming Feng, Global attractive set of neural networks with neutral item.
