Lie algebra (co)homology for supergroups
Lie algebra code (tar.gz compressed archive) is a collection of object-oriented python programs for calculating Lie algebra (co)homology for supergroups, in particular of the form psl(n|n). For psl(2|2) (co)homology is explored for the trivial, adjoint and several discrete series atypical representations (notation and results collected in psu112.pdf). For general psl(n|n) the trivial and singleton (for n even) representations are implemented (notation and results collected in pslnn.pdf).
