Subject: Software Release, Ginkgo v1.10.0

The Ginkgo team is proud to announce the new Ginkgo minor release 1.10.0.

Ginkgo is a high-performance numerical linear algebra library for
many-core systems, with a focus on solution of sparse linear
systems. It is implemented using modern C++, with GPU kernels
implemented for NVIDIA, AMD and Intel GPUs.

The highlights of the new release include:
- Support for bfloat16.
- Mixed precision support for distributed matrices
- Pipelined CG solver, and Chebyshev iteration solver
- OpenMP implementation of merge-path based SpMV

The release contains many more additions, improvements, and bug
fixes. A full list of the release changes can be found here:

Subject: New Book, Algorithms from THE BOOK, Second Edition

Algorithms from THE BOOK, Second Edition by Kenneth Lange

Most books on algorithms are narrowly focused on a single field of
application. This unique book cuts across discipline boundaries,
exposing readers to the most successful algorithms from a variety of
fields. Algorithm derivation is a legitimate branch of the
mathematical sciences driven by hardware advances and the demands of
many scientific fields. The best algorithms are undergirded by
beautiful mathematics. This book enables readers to look under the
hood and understand how some basic algorithms operate and how to
assemble complex algorithms from simpler building blocks.

Since publication of the first edition of Algorithms from THE BOOK,
the number of new algorithms has swelled exponentially, with the
fields of neural net modeling and natural language processing leading
the way. These developments warranted the addition of a new chapter on
automatic differentiation and its applications to neural net
modeling. The second edition also corrects previous errors, clarifies
explanations, adds worked exercises, and introduces new algorithms in
existing chapters.

In Algorithms from THE BOOK, Second Edition

•the majority of algorithms are accompanied by Julia code for
experimentation,
•the many classroom-tested exercises at the end of each chapter make
the material suitable for use as a textbook, and
•appendices contain not only background material often missing in
undergraduate education but also solutions to selected problems.

Subject: New Book, Hessenberg and Tridiagonal Matrices: Theory and Examples

Hessenberg and Tridiagonal Matrices: Theory and Examples
by Gerard Meurant

This is the only book devoted exclusively to Hessenberg and
tridiagonal matrices. Hessenberg matrices are involved in Krylov
methods for solving linear systems or computing eigenvalues and
eigenvectors, in the QR algorithm for computing eigenvalues, and in
many other areas of scientific computing (for instance, control
theory). Matrices that are both upper and lower Hessenberg are
tridiagonal. Their entries are zero except for the main diagonal and
the subdiagonal and updiagonal next to it.

Hessenberg and Tridiagonal Matrices: Theory and Examples presents
known and new results; describes the theoretical properties of the
matrices, their determinants, LU factorizations, inverses, and
eigenvalues; illustrates the theoretical properties with applications
and examples as well as numerical experiments; and considers unitary
Hessenberg matrices, inverse eigenvalue problems, and Toeplitz
tridiagonal matrices.

Subject: New Book, Robust Adaptive Control: Deadzone-Adapted Disturbance Suppression

Robust Adaptive Control: Deadzone-Adapted Disturbance Suppression
by Iasson Karafyllis and Miroslav Krstic

This book presents a solution to a problem in adaptive control design
that had been open for 40 years: robustification to disturbances
without compromising asymptotic performance. This original methodology
builds on foundational ideas, such as the use of a deadzone in the
update law and nonlinear damping in the controller, and advances the
tools for and the theory behind designing robust adaptive controllers,
thus guaranteeing robustness properties stronger than previously
achieved. The authors present all stability notions, old and new, that
are useful in adaptive control, provide numerous examples, and
contrast their analysis to landmark approaches to robustification of
adaptive controllers in prior literature.

This book develops the Deadzone-Adapted Disturbance Suppression (DADS)
control, a novel adaptive control method, and constructs a novel
robust identifier that can work in parallel with every direct adaptive
controller (not only DADS); it presents a wing rock instability
application of DADS and provides ideas for the extension of DADS to
cases not studied in the book.

Subject: Invitation: Finite Element Circus at GMU – October 17–18, 2025

Dear colleagues,

The Center for Mathematics & AI and the Digital Twin Lab at George
Mason University are pleased to host the upcoming Finite Element
Circus.

Dates: October 17–18, 2025

Location: George Mason University, Arlington Campus

Registration: Free, but required

Register here: https://cmai.gmu.edu/finite-element-circus/

About the FEM Circus:


The Finite Element Circus began in the 1970s, initiated by Ivo
Babuška, Bruce Kellogg, and Jim Bramble. This long-standing, biannual
event rotates among institutions in the U.S. and focuses on the theory
and applications of the Finite Element Method (FEM), numerical
analysis, and partial differential equations (PDEs).

Format:
• Talks are delivered by volunteers from the audience.
• Talk length depends on the number of speakers (typically 10–15
minutes).
• The order of talks is assigned randomly at the start of the meeting.
• Speakers are encouraged to prepare flexible talks that can be
adjusted in length.

More information and the history of the Circus can be found at:

We look forward to seeing you at GMU this fall!

Subject: PhD position in scientific machine learning at University of Wuppertal, Germany

Are you interested in developing novel scientific machine learning
models for a special class of ordinary and differential algebraic
equations? We are currently looking for a PhD candidate that supports
us in developing Gaussian processes based models with structure
preservation in port-Hamiltonian systems.

A PhD position is currently available in the Collaborative Research
Center 1701 "Port-Hamiltonian Systems" at University of Wuppertal,
Germany. Details on the CRC 1701 and the position can be found here:
