Actually, it's not the generators that I wish to have symbolic names for, but instead the elements within the generators. For instance, if the torus had a cellular decomposition of a 2-cell |

2015-09-26 15:21:07 -0500 | asked a question | Obtaining symbolic generators from homology() I need to compute the homology of a chain complex whose graded basis is a collection of formal symbols, say {a,b,c,…}. Does Sage have the capability to store a basis of symbols and express a homology class in terms of a symbolic class representative? I have been able to able to create a ChainComplex instance using matrices for the boundary maps. For example, However, I can't figure out how define symbols so that the resulting generators are symbols. Any ideas? |
