2009-01-18 Thread John H Palmieri
I have a first draft of a module which implements simplicial complexes, chain complexes, and their homology. It isn't perfect: it is limited by Sage's abilities to deal with modules over arbitrary commutative rings, or at least by my knowledge of Sage's abilities. Thus for example, you can define

As a first step I have made a new ticket for an improved spkg, which has "make check" test set in the makefile. If that looks OK I will try to get it merged upstream. So I would appreciate it if anyone can review #5018: http://trac.sagemath.org/sage_trac/ticket/5018. Marshall On Jan 18, 11:22
