Aims and Scope:

Reproducibility in mathematics and scientific computing has been gaining much attention lately, thanks in part to the dissemination of FAIR principles.  In numerical analysis, whether research results can be regenerated depends largely on the availability of the code implementing algorithms and access to publicly available data sets.  With this workshop, we aim to establish an initial benchmark collection and standards for key problems in matrix functions acting on vectors and exponential integrators, two highly active fields with overlapping interests, algorithms, and challenges. We also aim to encourage discussion among researchers from diverse theoretical and applied backgrounds, to help identify open questions and key directions for the future of these fields.
 
The fully in-person workshop will feature plenary lectures by experts in f(A)b and exponential integrators, as well as ample discussion sessions, in a non-traditional format.  Contributions from early career researchers will also be welcome.
 
 
Topics / keywords:
  • Matrix function times a vector (f(A)b), especially where f is the exponential, logarithm, signum, trigonometric functions, or fractional powers
  • Challenging data pairs (A,b) for both f(A)b and exponential integrators
  • trace(f(A))
  • moments: b*f(A)b
  • high-performance, highly parallelized, and energy-efficient methods for the above problems

Information on special volume in ETNA: "f(A)bulous progress on matrix functions and exponential integrators"

The volume will be edited by Andreas Frommer, Stéphane Gaudreault, Kathryn Lund, Marcel Schweitzer, and Daniel B. Szyld.  Submissions are due by 21 January 2024 and are open to all, regardless of participation in the workshop, but must touch on workshop themes.  Please follow the ETNA submission guidelines and send papers to Kathryn Lund (lund@mpi-magdeburg.mpg.de).
