Last time I looked into it a couple of years ago, the software landscape in this area consisted of some closed-source efforts mostly. It's great these two can be used easily now. (it's perhaps telling that dionysus only got its GPL license a month ago :-))
The only related effort that has some connection to Sage is Kenzo (https://github.com/gheber/kenzo), which has a persistent homology computation package; more precisely, it can compute persistent homology groups, which are basically reincarnation of groups in Leray spectral sequence (cf https://arxiv.org/abs/1308.0801). (I don't know what the exact status of Kenzo in Sage is ATM) Dima > > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
