Subject: Mass resignation of the Editorial Board of Journal of Approximation Theory
DECLARATION
Since 1968, Journal of Approximation Theory (JAT) has served the
mathematics community as one of the leading and most respected
journals in approximation theory and related areas of pure and applied
mathematics. In 2025, the Publisher at Elsevier made several decisions
that an overwhelming majority of the editors of JAT found deeply
problematic and likely to have a negative impact on the journal's
future. After efforts to resolve these concerns through discussions
with the Publisher proved unsuccessful, all but a handful of the
Editorial Board members resigned, as they found the Publisher's
decisions unacceptable. While the Publisher may attempt to keep the
brand alive, in our view the journal, as we knew it, has ceased to
exist. Nevertheless, we remain committed to preserving the spirit,
standards, and tradition that have long defined JAT.

RE: New Book: Delay Differential Equations and Applications to Biology,
Springer, March 2026. https://link.springer.com/book/10.1007/978-3-032-08645-7
Author: Fathalla A. Rihan
This book discusses the numerical treatment of delay differential equations and
their applications in bioscience. A wide range of delay differential equations are
discussed with integer and fractional-order derivatives to demonstrate their
richer mathematical framework compared to differential equations without
memory for the analysis of dynamical systems. The new edition introduces
advanced numerical techniques for solving pantograph-type DDEs, including
stability analyses. The book also integrates recent research on stochastic
models of DDEs, particularly from the fields of immunology and cancer
modeling. In addition, the book includes updated case studies from biological
and medical sciences, such as glucose-insulin interaction models and
infectious disease dynamics. This book is particularly valuable to
mathematicians, researchers, and professionals in the fields of mathematical
biology, life sciences, immunology, and epidemiology.

Subject: Induction Course for New Lecturers in the Mathematical Sciences 2026 - Registration open
Monday 14 - Tuesday 15 September 2026
Centre for Mathematical Sciences, Wilberforce Rd, Cambridge, CB3 0WA, UK
https://ima.org.uk/28710/induction-course-for-new-lecturers-in-the-mathematical-sciences-2026/
We are delighted to announce that in September 2026 the two‐day
Induction Course for lecturers new to teaching mathematics and
statistics within Higher Education will once again take place. The
Induction Course is delivered as an in‐person only activity to
maximise the opportunities for informal networking and discussion that
have long formed a highly valued part of this meeting. The Induction
Course for New Lecturers in the Mathematical Sciences has been
designed by the mathematics community so that it is ideally suited for
anyone who is new to, or has limited experience, teaching mathematics
or statistics within UK higher education. It will be delivered by
individuals with significant experience of teaching in the
mathematical sciences and will focus upon the specific details and
issues that arise in mathematics and statistics teaching and learning
within higher education.
Topics include:
• Lecturing.
• Supporting student learning.
• Making teaching interactive.
• Assessment, examinations and feedback.
• Linking teaching & research.
• Using technology to enhance teaching and learning.
• Using examples and mathematical problem solving.
• Teaching statistics and its applications.
Session Facilitators
Those leading the sessions at the Induction Course are all experienced
teachers of mathematics within UK higher education. They include:
• Lara Alcock (Loughborough University)
• Sam Fearn (Durham University)
• Joel Haddley (University of Liverpool)
• Howard Haughton (King’s College London)
• Ioanna Papatsouma (Imperial College London)
• Peter Rowlett (Sheffield Hallam University)

Subject: Workshop on Neuro-symbolic AI, Mathematical Reasoning and Agents, Sep 2026
Date: September 14-17, 2026
Location: WIAS Berlin
Registration Deadline: July 6, 2026
This workshop brings together researchers from academia and
industry working at the intersection of neuro-symbolic AI,
mathematical reasoning, and intelligent agents. The focus is on
architectures that combine logical and probabilistic reasoning with
deep learning, knowledge graphs, and large language models, with
particular emphasis on formal and informal mathematical reasoning,
world models for agents, and continuous/continual learning.
We invite contributions on topics including (but not limited to):
- Neuro-symbolic methods
- Logical/tensor-based frameworks for agents and world models
- Integration of symbolic reasoning with LLMs and tool-using
agents
- Continual learning of concepts, rules, and mathematical
structures
- Industrial case studies (e.g. robotics, digital twins, safety-
critical systems)
The workshop will feature invited talks and contributed
presentations, with the goal of discussing recent developments and
open challenges and fostering collaboration between theory-oriented
groups and research-driven industrial labs.

The MATHEXP team at Inria Saclay Centre (https://www.inria.fr/en/
mathexp) is looking for outstanding candidates to apply for a Marie
Skłodowska-Curie Postdoctoral Fellowship (MSCA-PF) in the area of
symbolic-algebraic and semi-numerical computational methods.
Our research focuses on the study of functions defined by
functional equations—such as special functions, D-finite functions,
and generating functions—with a strong emphasis on experimental
mathematics. We work at the interface of:
- algorithm design
- symbolic computation and
- applications across combinatorics, number theory, statistical
physics, quantum mechanics, and algebraic geometry
Research directions include:
- Algorithms for differential and functional equations
- Combinatorial walk models & constrained graph enumeration
- Feynman integrals and related problems
- Extending symbolic-numeric methods to new application domains
We are particularly interested in candidates who:
- have a strong background in mathematics or related areas
- are motivated to use symbolic computation as a central tool
- wish to develop a research program combining algorithmic methods
with domain-specific applications
If you are interested in applying for an MSCA-PF with us, feel free
to get in touch to discuss potential proposals:
