### Steps To Reproduce
I tried to compile sage 10.2 and failed at several packages involving cython errors
Compilation failed at packages cylp and p_group_cohomology (maybe more, but I am not cont…

Schemes are ticking along nicely, as is commutative algebra. Currently we still don't have schemes in mathlib, or etale maps of rings, but it is not hard to imagine them being there at some point in t…

Using the ZGroup module and symbolic manipulation was very helpful to simplify the cochains codomain complexity. Similarly, symbolic manipulation for the cochain domain will enable us to investigate h…

I noticed this, @tpannila :

Proof.

At least the definition of cohomology of a type X can be generalized to dependent coefficients. This means the coefficients are given as a dependent type `F : X -> Sp` with values in the type of spect…

The `TranslationSurface.rel_deformation(self, deformation, local=False, limit=100)` method is a special case of the pyflatsurf `+` operator that implements any deformation. Once a proper class for the…

- starting from a guess (absolute) tangent space $V \subset H^1(M; \mathbb{R})$ there are two purely algebraic ingredients that could be used to make it bigger
