Equivariant Sugrue conjecture on homological dimension of rational G-sheaves

Let GG be a profinite group acting on a GG-space XX. Suppose that XX has finite Cantor--Bendixson rank and non-empty perfect hull. Equivariant Sugrue conjecture. The homological dimension of rational GG-sheaves over XX 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, X=SGX=\mathcal{S} G, predicts that the category of rational Weyl-GG-sheaves has infinite homological dimension.
