On the quasi-hereditary property for staggered sheaves
Pramod N. Achar
Let G be an algebraic group over an algebraically closed field, acting on a variety X with finitely many orbits. "Staggered sheaves" are certain complexes of G-equivariant coherent…
Staggered sheaves on partial flag varieties
Pramod N. Achar, Daniel S. Sage
Staggered -structures are a class of -structures on derived categories of equivariant coherent sheaves. In this note, we show that the derived category of coherent sheaves on…
Springer correspondences for dihedral groups
Pramod N. Achar, Anne-Marie Aubert
Recent work by a number of people has shown that complex reflection groups give rise to many representation-theoretic structures (e.g., generic degrees and families of characters),…
An order-reversing duality map for conjugacy classes in Lusztig's canonical quotient
Pramod Achar
We define a partial order on the set of pairs {(O,C)}, where O is a nilpotent orbit and C is a conjugacy class in Lusztig's canonical quotient of A(O). We then show that there is a…
