Authors:

Ramesh, L., ramesh@mathematik.uni-kl.de

Overview:

Procedures for and involving computing Schreyer resolution of modules over the exterior algebra

Procedures:

D.15.22.1 schreyerSyzExt		(refined) Schreyer syzygy of a module over the exterior algebra
D.15.22.2 sresExt		free resolution of module m over the exterior algebra using refined Schreyer alg
D.15.22.3 mresExt		minimal free resolution of module m over the exterior algebra using refined Schreyer alg
D.15.22.4 sheafCohBGGsres		cohomology of twists of the coherent sheaf F on P^n associated to coker(M). The range of twists is determined by l,h.
