Subject: New Book, Modeling Nonlinear Dynamics from Equations and Data—with Applications to Solids, Fluids, and Controls
Modeling Nonlinear Dynamics from Equations and Data—with Applications
to Solids, Fluids, and Controls by George Haller
“George Haller provides a substantial literature overview which, in
combination with his many contributions, results in the first book on
spectral model reduction techniques. He covers basic theory for both
linear and nonlinear problems and model- and data-driven techniques,
and he demonstrates the method’s excellent behavior on nontrivial
problems.”
– Jan S. Hesthaven, Karlsruhe Institute of Technology (KIT)
“This is an exciting topic and a powerful method that already has and
will continue to have an impact on any field where model reduction is
a key ingredient or a central concern. The content is presented in a
logical order, from the equation-based to the data-driven version of
the method to applications that progressively increase in complexity.”
– Peter Schmid, KAUST
This concise text presents an introduction to the emerging area of
reducing complex nonlinear differential equations or time-resolved
data sets to spectral submanifolds (SSMs). SSMs are ubiquitous
low-dimensional attracting invariant manifolds that can be constructed
systematically, building on the spectral properties of the linear part
of a nonlinear system. The internal dynamics within SSMs then serve as
exact, low-dimensional models with which the full system evolution
synchronizes exponentially fast.
SSM-based model reduction has a solid mathematical foundation and
hence is guaranteed to deliver accurate and predictive reduced-order
models under a precise set of assumptions. This book illustrates the
power of SSM reduction on a large collection of equation- and
data-driven applications in fluid mechanics, solid mechanics, and
control.

Subject: Autumn School on SciML & Numerical Methods (Amsterdam, 27-31 Oct 2025)
Dear colleagues,
We are pleased to announce that registration is still open until the
1st of June 2025 for the Autumn School on Scientific Machine Learning
and Numerical Methods, held as part of the CWI Research Semester
Programme on Bridging Numerical Analysis and Scientific Machine
Learning: Advances and Applications.
Dates: 27 – 31 October 2025
Location: Centrum Wiskunde & Informatica (CWI), Amsterdam
This week-long event will feature mini-courses by leading researchers
in the field, offering participants an in-depth introduction to key
topics at the interface of numerical methods and machine learning. It
is aimed at PhD students, postdocs, and early-career researchers, but
is open to all with an interest in the topic.
More information and registration:

Subject: PhD / PostDoc position in Numerical Linear Algebra / HPC, Germany
The Computational Mathematics Group at the TU Munich in Heilbronn is
looking for a PhD / Post candidate with a focus on numerical linear
algebra for high performance computing. Knowledge in C/C++ and GPU
programming as well as a strong background in linear algebra is
expected. Experience in scientific software development is a
bonus. Research can be application- specific or generic on the design
and implementation of mixed precision algorithms, randomized linear
algebra, batched routes, etc.
