WebThe name perverse sheaves is a bit misleading,because neither they are sheaves, nor they are perverse. Perverse sheaves live on spaces with singularities. A perverse sheaf on a topological space Xis actually a bounded constructible complex in the derived category that satisfies certain dimension conditions on its cohomology sheaves.

In this case perversity p(x) is assigned only to orbits of G (including “generic orbits”), since an equivariant sheaf is automatically smooth along the orbits. More generally, the perverse t-structure can be constructed for coherent ... grammarly document editor
