B.6 ncdecomp_lib

Library:
ncdecomp.lib
Purpose:
Central character decomposition of a module
Authors:
Viktor Levandovskyy, levandov@mathematik.uni-kl.de.

Overview:
This library presents algorithms for the central character decomposition of a module (in other words, a
decomposition into generalized weight modules with respect to the center). Based on ideas of O. Khomenko and V. Levandovskyy.

Procedures:

B.6.0.1 CentralQuot  central quotient I:G,
B.6.0.2 CentralSaturation  central saturation ((M:T):...):T) ( = M:T^{infty}),
B.6.0.3 CenCharDec  central character decomposition of I w.r.t. C
B.6.0.4 IntersectWithSub  intersection of M with the subalgebra, generated by pairwise commutative elements.
