Great, just cc me on the ticket when you are able to get to it. I might be able to also take your toy implementation and port it over, but I likely won't have time until February. Best, Travis On Thursday, November 28, 2019 at 1:38:33 AM UTC+10, Salvatore Stella wrote: > > Hi Travis (and all),

Hi Travis (and all), I already have a toy implementation and it is indeed worth including in sage. Given a chain complex it produces a new chain complex that has the same homology but whose differentials are much much smaller. You can look at it here: https://github.com/Etn40ff/chromatic_symmetr

Sage is not using very sophisticated methods for computing homology. If anyone wants to implement something better, they are certainly welcome to. I may try to look at the paper, but it may take me a while to get to it. -- John On Wednesday, November 13, 2019 at 4:48:18 PM UTC-8, Salvatore Ste
