(computational methods in Lie theory)
Introduction
In Lie theory, as in many other fields in mathematics, the power
of modern computers has given an impetus to research
on various problems which are hard from a computational
point of view. A few examples of the topics are
computations involving root systems, Weyl groups, Coxeter
groups, Kazhdan-Lusztig polynomials, decompositions of tensor
products of representations, classifications in geometric
invariant theory, normal form problems, special base computations in
Lie algebras and representation spaces.
Many ad hoc programs have been written that usually
serve the author for one or a few individual problem instances
but have the potential of being useful for a much wider group of
researchers. This and the fact that many implementations of the
same algorithm have been found to occur lead us to believe that
some organization and collaboration in this area is called for.
Therefore at a workshop on Computational Methods in Lie Theory
at Monte Verita (March 1993), a network of individuals and groups
interested in the theory, methods, and applications of
computations in Lie theory has been established. (See also the
