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(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).
Schur-Weyl duality multiplicity
SAGE multiplicity code computes the various multiplicities used in Diagonal free field matrix correlators, global symmetries and giant gravitons using the SAGE computer algebra system.
Correlators in U(2) sector of N=4
