This patch adds method minimal_representatives and extends the functionality of bruhat_poset and bruhat_graphs.
Let W be a finite Weyl group and let W_S be the subgroup of W generated by reflection…

Gudhi doesn't compute degree 1 homology of a 1-dimensional simplextree by default.
Minimal example :
```python
st = gd.SimplexTree()
st.insert([0,1,2],1)
st.remove_maximal_simplex([0,1,2])
st.pe…

Tabulate properties of well-known 2d CFTs. This should include central charge, chiral algebra, operator content, structure constant. The list of CFTs should include:
- Liouville,
- generalized minim…

In order to get cohomology (deRham, Ext, Tor all things that M2 does well) in sage we need to get basic classes for graded rings and modules. We should also implement Proj(S) like Spec for commutati…

In other words: Do we have $H^1(\mathbb A^1,\mathbb Z)=0$ ?
Using reasoning from 2.2 in the [A1-homotopy draft](https://felix-cherubini.de/A1-homotopy.pdf), this would also imply that $B\mathbb Z=S^1…

The Moseley ring of a hyperplane arrangement is the equivariant cohomology ring of the hyperplane arrangement equipped with a torus action. See https://arxiv.org/abs/1110.5369 for details.
