[ANN] Aldor & Axiom / OpenAxiom / FriCAS Workshop 2008
Martin Rubey
Aldor & Axiom Workshop 2008
part of
RISC Summer 2008
Hagenberg, Austria
24-26 July 2008
The workshop aims at a cooperation of Aldor, Axiom, OpenAxiom, and FriCAS
developers with developers of packages written for other Computer Algebra
Systems, and mathematicians that would like to use a computer algebra system to
perform experiments.

Topics
------
Similar to 2006 and 2007, the workshop will be organized as a mixture of
talks and discussions. We will begin with an introduction to Axiom /
OpenAxiom / FriCAS and the Aldor language, including a comparison with the
approach employed by Sage and Python.
We then plan to cover the following topics:
Aldor, SPAD, and the interpreter
- work on SPAD (eg., allow arbitrary conditional exports),
- work on the interpreter (eg., it's signature selection algorithm), and
- improve the Axiom / OpenAxiom / FriCAS - Aldor interaction (eg., make
Axiom / OpenAxiom / FriCAS understand Aldor's extend or dependent
signatures generated in Aldor code).
interaction of Axiom / OpenAxiom / FriCAS with other systems
We would like to explore the possibility and the usefulness of reusing
third party code like PARI, GAP, Polymake, etc., but also interfacing with
Sage.
problems implementing mathematics in Aldor and SPAD
We would like to tackle some particularly challenging implementation
problems, including
- combinatorial species - the multisort case,
- how to organize domains and categories for recurrences and functions,
- how to organize aggregates and matrices, in particular how to ensure
efficient looping over aggregate elements, etc.
