Dear Forum:
I really appreciate if someone can help with this question:
1. I want to define the differential d in the polynomial ring GF(2)[x_1,x_2]
given by:
- d(x_1)=0.
- d(x_2)=x_1^2.
- d(p,q) = pd(q) + d(p)q
2. and then compute it's cohomology: kernel, and image.
Off course I need some examples more complicated, I just to know if this is
possible in GAP, if there is a function, or If Should I program this by
myself?
Thank you so much for your time.
