Subject: Erik Bollt (1967–2025)
Erik Bollt passed away suddenly on December 7, 2025, at the age of 58,
while cross-country skiing near Potsdam, New York. He left us far too
young.
Erik (who liked to note that his surname is spelled B-o-l-l-t, not the
more common Bolt) was born in Maryland. He studied at UC Berkeley and
the University of Colorado Boulder, where he became the first student
to earn a PhD from the newly formed applied mathematics program. After
appointments at the U.S. Military Academy and the U.S. Naval Academy,
Erik spent 23 years as a professor at Clarkson University. He was
deeply proud of his role as a teacher and advisor and was especially
known for his love of mathematics. Over his career, he supervised 34
graduate students and postdoctoral researchers, whom he regarded as
family.
Erik was an extraordinarily prolific and imaginative researcher,
authoring more than 250 publications, a textbook, and accruing over
10,000 citations. He had a rare ability to connect classical dynamical
systems and analytical tools with emerging computational and
data-driven methods. His work spanned chaos, networks, computational
mathematics, and machine learning.
I had the privilege of knowing Erik as a friend for a few years, and
we had recently begun a collaboration. I admired his intellectual
creativity, warmth, generosity, and infectious excitement for
ideas. Erik visited Cornell several times over the years (two of his
sons were Cornell undergraduates), and it was always a pleasure to see
him. In October, I visited Erik at Clarkson, where I saw firsthand the
vibrant research environment he had built. Our conversations were
always animated, curious, and full of laughter; Erik had a way of
making mathematics feel alive and joyful.
Erik is survived by his wife of 30 years, his three sons, his mother
Nina, his sisters Marci and Julie, and his extended family.

Subject: New Book, Practical Nonconvex Nonsmooth Optimization
Practical Nonconvex Nonsmooth Optimization by Frank E. Curtis and
Daniel P. Robinson
This book provides a clear and accessible introduction to an important
class of problems in mathematical optimization: those involving
continuous functions that may be nonconvex, nonsmooth, or both. The
authors begin with an intuitive treatment of theoretical foundations,
including properties of nonconvex and nonsmooth functions and
conditions for optimality. They then offer a broad overview of the
most effective and efficient algorithms for solving such problems,
with a focus on practical applications in areas such as control
systems, signal processing, and data science.
Practical Nonconvex Nonsmooth Optimization focuses on problems in
finite- dimensional real-vector spaces, avoiding the need for a
background in functional analysis. It introduces concepts through
nonconvex smooth optimization, making the material more accessible to
those without extensive experience in convex analysis. A
conversational tone is used throughout, with technical proofs placed
at the end of each chapter to help readers understand the core ideas
before engaging with detailed arguments.

Methods for Evolutionary PDE - HONOM 2026

Conference fee: 610 EUR (full), 305 EUR

Themes of the
conference:
Many processes in science and engineering can be
described by nonlinear time-dependent PDE systems. Accurate and
robust numerical methods are required for their solution, since
these PDE can exhibit smooth, small and large-scale features as
well as discontinuities and singularities at the same time. In
addition to the classical requirement of conservation, high order
of accuracy in both space and time is of fundamental importance to
properly resolve all physical processes involved. The real
challenge, therefore, still remains to construct high-order
accurate and at the same time robust and stable nonlinear and non-
oscillatory schemes. Significant advances have been made in this
direction in the last decades, pioneered by TVD (Total Variation
Diminishing) methods, ENO and WENO schemes, as well as nonlinear DG
finite element methods with appropriate limiters.

Subject: PhD studentship in Scientific Computing, September 2026, UCL and STFC ALC, UK
Applications are invited for a PhD studentship joint between UCL CCMI
CDT and STFC ALC commencing in September 2026: "Hybrid
Parallel-in-Time and Machine Learning Approaches to Accelerate
Simulations for Many-Body Quantum Systems"
Understanding multi-body quantum systems is both of independent
interest but also crucial for interpretation of experiments conducted
to investigate material properties. The mathematical models
underpinning the simulations require the solution of
integro-differential equations. However, solving these equations
accurately is extremely computationally demanding due to the presence
of a memory term which adds a global aspect to otherwise local
computations. By combining physics knowledge with modern computational
techniques, this project will enable larger systems to be accurately
studied over longer time horizons, expanding applicability of
state-of-the-art methods to study advanced quantum materials and
phenomena. This PhD project will combine two cutting-edge approaches:
parallel-in-time computing and machine learning. Parallel-in-time
methods break the simulation into smaller time segments that can be
solved simultaneously, dramatically reducing computation time. Machine
learning could be used to improve the efficiency of these simulations
by learning simplified models of the system's behaviour, allowing fast
inference and/or improved accuracy of the simulations by providing a
framework for combining with data from other sources.
CCMI is an EPSRC Centre for Doctoral Training joint between UCL and
Imperial College. The Science and Technology Facilities Council (STFC)
operate world class national science facilities including the Central
Laser Facility and ISIS Muon Neutron Source. The Scientific Computing
department and Ada Lovelace Centre at STFC work to maximise the
scientific impact of these national facilities through expertise in
scientific software.
The successful applicant will be working with Marta Betcke (UCL),
Tyrone Rees (Computational Maths, STFC), and Paolo Trevisanutto
(Physics, STFC), will be participating in all CCMI CDT activities, and
will spend 50% of their working (in person and hybrid) at STFC
collaborating with the teams in Maths and Physics.
To apply, please complete the application to the CCMI CDT by 12th
January 2026 at 17:00 (GMT). At this stage, you will not be asked to
choose the project, but please indicate your interest in this position
