Equivariant Sugrue conjecture on homological dimension of rational G-sheaves
Equivariant Sugrue conjecture on homological dimension of rational G-sheaves
Let be a profinite group acting on a -space . Suppose that has finite Cantor--Bendixson rank and non-empty perfect hull. Equivariant Sugrue conjecture. The homological dimension of rational -sheaves over is infinite. This is an equivariant version of a conjecture of Sugrue concerning spaces with finite Cantor--Bendixson rank and non-empty perfect hull. The corresponding assertion for the space of closed subgroups, , predicts that the category of rational Weyl--sheaves has infinite homological dimension.
