Subject: Advances in Approximation Theory (AAT) has arrived
Dear Readers of NA Digest:
Probably you know already that "Journal of Approximation Theory"
(JAT), as we knew it, is dead, see jat.nevai.us. Most of JAT's former
editors joined forces to launch a new online successor of JAT that we
used to love and respect (but not anymore). It is published by
Stanford University Press and it is called "Advances in Approximation
Theory" (AAT) with Martin Buhmann, Feng Dai, András Kroó, and Sergey
Tikhonov as the Editors-in-Chief, see,
https://aat.journals.sup.org.
I and our editors will be super appreciative and grateful if you
helped us to make AAT viable, successful, and at least as respected as
JAT used to be, by submitting your papers related to Approximation
Theory to AAT.
You can register as an Author, Reviewer, and Reader at
https://aat.journals.sup.org/index.php/aat/user/register
Please contact AAT at aat@nevai.us if you have any questions.
We are looking forward to hearing from you and to processing your
papers at AAT. In addition, please spread the word among your
colleagues, coauthors, and friends. Please inform them and encourage
them to submit papers to AAT.
Gratefully, Paul Nevai

Subject: MFEM Version 4.10
Version 4.10 of MFEM, a lightweight, general, scalable C++ library for
finite element methods, is now available at: https://mfem.org.
The goal of MFEM is to enable high-performance scalable finite element
discretization research and application development on a wide variety
of platforms, ranging from laptops to exascale supercomputers.
Some of the new additions in version 4.10 are:
- GPU partial assembly for simplicial Bernstein H1 mass and diffusion.
- FindPointsGSLIB point search and interpolation on surface meshes.
- Expanded GPU kernels and GPU-aware MPI communication.
- Parallel nonuniform anisotropic refinement on quad and hex meshes.
- NVIDIA cuDSS sparse direct solver and MPI-distributed Ginkgo solvers.
- GridFunction extrema estimates by piece-wise linear bounds.
- Complex-valued mixed sesquilinear forms.
- Positive-weight quadrature rules on triangles and tets.
- Gmsh 4.1 mesh format support (ASCII and binary).
- 7 new examples and a new electrostatic Particle-In-Cell miniapp.
The MFEM library has many more features, including:
- 2D and 3D, arbitrary order H1, H(curl), H(div), L2, NURBS elements.
- State-of-the-art MPI scalability and GPU acceleration.
- Conforming/nonconforming adaptive mesh refinement (AMR), including
anisotropic refinement, derefinement and parallel load balancing.
- Galerkin, mixed, isogeometric, discontinuous Galerkin, hybridized,
and DPG discretizations.
- Support for triangular, quadrilateral, tetrahedral and hexahedral
elements, including arbitrary order curvilinear meshes.
- Scalable algebraic multigrid, time integrators, and eigensolvers.
- Interactive OpenGL visualization with the MFEM-based GLVis tool.
MFEM is developed in CASC at Lawrence Livermore National Laboratory and is
freely available under a BSD license. For more details, see the documentation
at https://docs.mfem.org/4.10 and the full CHANGELOG at

Subject: Call for participation: Shaping the future of NLA in Europe, January 18-22, 2027, Barcelona
The workshop “Shaping the future of Numerical Linear Algebra in Europe” will
be held on January 18-22, 2027, at the Centre de Recerca Matemàtica in
Barcelona.
The workshop is promoted by the Topical Activity Group (TAG) E-ANLAMA
(Applied and Numerical Linear Algebra, Matrix Analysis and Applications) of the
European Mathematical Society (EMS), and it is part of the project with the
same name. This project, funded by the EMS, aims to strengthen and promote
research collaboration between researchers based in different countries (also
outside the EU), to foster the involvement of young researchers within
established research groups of the TAG, and to create cross-national research
teams on topics of high current interest in NLA and applications. In particular,
the topics of this workshop are the following:
- Randomized NLA.
- Multilinear Algebra in Machine Learning.
- NLA in High Performance Computing.
- NLA in Industry.
- Quantum algorithms in NLA.
The workshop will include introductory and research-oriented talks on these
topics by renowned researchers in the field. There will also be sessions for
contributed talks by other participants, as well as for more interactive activities,
such as small group discussions or problem-driven working sessions.
A limited number of grants for early career researchers are available.
We strongly encourage you to attend the meeting. Everybody is welcome!
For more information and registration, please go to the webpage of the
workshop:
