For very large and challenging computations, most of the elements of the face lattice contain rather few atoms/bits. With little changes to the code, we can just collect the non zero chunks (64,128 …

Currently, the input of `add_simplices_from` needs to be a list of simplices, each simplex of the format `(1,2,3)` or with attributes, say `(1,2,3, {"color": "red}`. The `len` of the simplex is then 3…

This ticket parallelizes the f-vector for polytopes.
Each thread has its private structure with which it does partial jobs. Depending on the parallelization depth, there is one job per face of fixe…

Usual reason...
This one is a bit more complicated than usual : the Windows toolchain has changed ; however, I do not have a Windows system to test this.

This is tangentially related to #684. I'm trying to write a C++ function using 3D alpha complexes that can be wrapped in python. So, I take as input a 2D vector of doubles (3D coordinates of points) a…

This patch adds a cohomology ring to toric varieties. This is then used for characteristic classes.
I'm using the usual description of the rational cohomology ring via the Stanley-Reisner ideal of …

We also remove some module-level imports of `AA` etc.
Split out from #32432.

Rationale : R (standard package) requires libcurl (and possibly the curl executable), but stopped to package it with version 3.3.0.
