Subject: Karl Strehmel (1934 - 2023)


On 12 December 2023, our highly esteemed colleague Karl Strehmel,
university professor and founder of the NUMDIFF conference series,
passed away after a short, serious illness.

Karl Strehmel was a great mathematician and scientist who, even in
times of German and European division, worked with great commitment
and skill to promote international scientific cooperation that
transcended borders. In the early 1980s, he founded the "Numerical
Treatment of Differential Equations" seminars, which have since
brought together many leading international experts in this field at
the NUMDIFF conferences at Martin Luther University. We will
commemorate him at NUMDIFF-17 in September 2024.

We remember with gratitude an academic teacher who opened up new
horizons and inspired enthusiasm for his field.

Subject: New Book, IAHR Water Monograph Series


Variational approach to water wave modelling"
by Didier Clamond, Denys Dutykh, and Dimitrios Mitsotakis.

This book has been published in open access, and the full text is
freely accessible for everyone at this URL address:
https://www.iahr.org/index/detail/659

This monograph offers a comprehensive exploration of water wave
dynamics through the innovative lens of relaxed variational
principles. The authors present a nuanced approach to modelling both
nonlinear dispersive and non-dispersive waves, advancing our
understanding of fluid dynamics. A pivotal aspect of this work is the
application of the relaxed variational principle, providing a robust
mathematical foundation for the study of water waves. Additionally,
the monograph delves into sophisticated numerical techniques,
including finite volume and pseudo- spectral schemes, which are
instrumental in simulating these complex wave phenomena. This text is
an invaluable resource for researchers and practitioners in fluid
mechanics, offering new perspectives and methodologies for tackling
the challenges of water wave modelling.

Subject: Fast and Stable Roots of Polynomials, ONLINE, Feb 2024


Raf Vandebril, KU Leuven, Numerical Analysis and Applied Mathematics
(NUMA), Fast and Stable Roots of Polynomials via Companion Matrices
Tuesday February 6, 2024, 5pm

We present a fast and stable algorithm for computing roots of
polynomials. The roots are found by computing the eigenvalues of the
associated companion matrix. A companion matrix is an upper Hessenberg
matrix that is of unitary-plus-rank-one form, that is, it is the sum
of a unitary matrix and a rank-one matrix. When running Francis's
implicitly-shifted QR algorithm this property is preserved, and
exactly that is exploited here. To compactly store the matrix we will
show that only 3n-1 rotators are required, so the storage space is
O(n). In fact, these rotators only represent the unitary part, but we
will show that we can retrieve the rank-one part from the unitary part
with a trick. It is thus not necessary to store the rank-one part
explicitly. Francis's algorithm tuned for working on this
representation requires only O(n) flops per iteration and thus O(n^2)
flops in total. The algorithm is normwise backward stable and is shown
to be about as accurate as the (slow) Francis QR algorithm applied to
the companion matrix without exploiting the structure. It is also
faster than other O(n^2) methods that have been proposed, and its
accuracy is comparable or better.

The paper accompanying this research received SIAM's outstanding paper
prize in 2017.

Subject: PhD Position, Low Rank Approx for Tensor Modeling, Inria Sophia Antipolis


TENORS (Tensor modEliNg, geOmetRy and optimiSation) is a Marie
SkBodowska-Curie Doctoral Network / Joint Doctorate (2024-2027),
offering 15 PhD positions starting from September 2024. The objective
of TENORS is to conduct advanced research that addresses critical
challenges in the fields of tensor modeling and computation, joining
forces from algebraic geometry, global optimisation, numerical
computation, high performance computing, data science, quantum
physics.

One position in TENORS is around low-rank representations of numerical
solutions of high-dimensional partial differential operators, for use
in modeling and optimization. In particular we aim at accelerating
isogeometric discretizations that are based on tensor-product or
hierarchical splines. Solving using grid-based methods suffers from
the, so called, curse of dimensionality and scales badly with the
number of knots in the spline representation. We will tackle this
problem using tensor decomposition by means of the moment method. The
problem discretization will be carried out using tensor-product spline
bases, enhanced by the use of low-rank approximation of the
computational domain and the numerical solution. Consequently, the
computational complexity of the method will depend on the resulting
tensor rank and will be linear in the grid dimensions. In a second
phase the discretization will be enriched using hierarchical splines,
for localizing the problem and for gaining efficiency in high
dimensional instances

The candidate will work at INRIA at Universite Cote d'Azur in Sophia
Antipolis, and will spend one semester at the University of Florence
as well as few months at Artelys Paris.

Subject: PhD Positions, Neural Tensor Train Networks, KU Leuven/UCLouvain


We are looking for PhD candidates to fill 2 fully-funded 4-year PhD
positions. One position is in the NUMA unit at the Department of
Computer Science, KU Leuven, Belgium, while the other position is in
the ICTEAM institute at the Mathematical Engineering Departement,
UCLouvain, Belgium. We seek candidates with a Master's degree in
Applied Mathematics, Computer Science, Data Science, and/or (Applied)
Mathematics, broadly defined.

The PhD candidates will carry out fundamental scientific research on
the NTTN project of professors E. Massart (UCLouvain) and N.
Vannieuwenhoven (KU Leuven). This project will develop new machine
learning models and corresponding training algorithms to tackle two
current challenges in data science: growing primary energy consumption
and proliferation of biases in training data. We aim to tackle these
fundamental challenges through an interesting blend of deep learning,
tensor decompositions, Riemannian optimization, and representation
theory.

Applications will be considered as soon as we receive them. The
procedure may be closed earlier than the final application date (March
26, 2024) in case 2 excellent candidates have been found. Some
flexibility in the starting date of the position is possible, but it
must be in 2024. The ideal starting date is before October 2024.

Subject: REU Positions, Big Data with HPC, ONLINE, Jun-Aug 2024


Please forward to undergraduate students interested in AI and HPC!

We are organizing an NSF-funded REU (Research Experiences for
Undergraduates) Site program at UMBC: Online Interdisciplinary Big
Data Analytics in Science and Engineering. It is a purely online
program open to students from the entire nation. The 8-week program
will include training in fundamentals of HPC software (MPI) and
productivity tools (SLURM) on large distributed-memory clusters with
CPUs and GPUs as well as Data Analytics applications like Tensorflow,
Keras, PyTorch, Horovod. Each student will be paid a stipend of
$5,600 for participation and provided with opportunities to present
their work at conferences. We are looking for students from all STEM
disciplines and particularly also for students who are interested in
gaining Big Data, HPC, and application experience.

More information can be found at https://bigdatareu.umbc.edu
and the PDF flyer there. The application deadline is 03/01/2024.
The two project topics planned for summer 2023 are
(1) Artificial Intelligence and Big Data Research for Earth Applications;
(2) Machine Learning in Real-Time Imaging for Proton Radiotherapy.

Both projects are in collaboration with outside collaborators to give
an interdisciplinary research experience. Each team of participants is
supported by a dedicated graduate assistant and will publish a
technical report in the HPCF Tech. Rep. series. Every team in past
years has additionally published at least a conference paper.

Please distribute this opportunity to undergraduate students and
additional colleagues/communities. Thank you very much!
