That definitely is not a bug in CombinatorialFreeModule, so there shouldn't be anything changed there. It is doing what it is told: that its indexing set is in finite sets. I would say the bug is purely in the DisjointUnionEnumeratedSets not doing a full check of its member sets. Best, Travis

2020-06-20 Thread Franco Saliola
Hello, I am trying to create a binary for CentOS 7. I have not been able to find a guide on how to create binaries, so I've been piecing together the procedure from various sources and so I have a few questions. First of all, my goal is to use sage on a cluster running CentOS 7. I can't insta

[sage-devel] Parallelization of Wedge Product Computation

2020-06-20 Thread Michael Jung
Dear Sage-Developers, in the SageManifolds part, most component-wise computations can be performed on multiple cores. However, the wedge product has not been parallelized yet. But since I need this for some computations in "higher" dimensions, I want to contribute this to the project. I had alr
