Description (last modified by hivert) (diff)
The goal of the patch is to adapt SymmetricGroupAlgebra? to categories and to add some improvements. The patch improve SymmetricGroupAlgebra? in two ways:
- SymmetricGroupAlgebra? is now in the category FiniteDimensionalAlgebraWithBasis?. Note: A forthcomming patch from Valentin Feray will put it in the correct GroupAlgebras? category;
- When creating SGA(n) a coercion from SGA(n-1) is declared.
I'm submitting the patch on behalf on Nicolas after reviewing it.
Depends on the categories framework #5891, #6136.
Cheers,
Florent
