Software-related Projects
SINGULAR and PLURAL . I have been involved in the development of these systems since 1997. In 2005 PLURAL became an integral part of SINGULAR . See more at My Singular. There are several important variations of non-commutative Gröbner bases, on which I either already work or plan to work in the near future. News: ongoing development of the following projects:
SINGULAR : LETTERPLACE - Gröbner bases for modules over free and finitely presented algebras.
SINGULAR : LOCAPAL - Gröbner bases and basics over OLGA's, that is over certain (rational) localizations of G-algebras.
D-modules suite: several libraries, providing powerful implementations to the algorithms of computational D-module theory and algebraic analysis.
C L I P S a.k.a. Control Library In Plural and Singular, formerly supported by the Forschungsschwerpunkt "Mathematik und Praxis". Current state: in the SINGULAR library control.lib there have been implemented important (and easy-to-use) functions for systems with constant coefficients (that is, at present we work over commutative rings). Future plans: extend the functionality to the cases of polynomial and rational coefficients.
Databases, Benchmarking, Collection of Examples
The development of the database Gröbner Bases Implementations. Functionality Check and Comparison was initiated by me and enthusiastically supported by Bruno Buchberger during the Gröbner Bases Special Semester in 2006 at RISC. The database is currently being filled up with the data on contemporary computer algebra systems. Thanks to Camelia Rosenkranz for its programming!
SymbolicData. A project maintained by Hans-Gert Gräbe from Leipzig. We have tested the possibility to handle non-commutative PBW-like structures back in 2004. News:
The toolbox has been updated by H.-G. Gräbe with the XML-like syntax. We are working on bringing various non-commutative test sets together in the framework of SymbolicData.
There is ongoing work to provide FreeAlgebra types of examples and to implement connections to/from SINGULAR : LETTERPLACE , Magma, GAP and Bergman.
