On Perverse sheaves of a Coxeter hyperplane arrangement of type
Umesh V Dubey, Subham Sarkar
Kapranov and schechtman gave quiver description of perverse sheaves on real hyperplane arrangements. We used this description to relate the perverse sheaves on Coxeter hyperplane a…

Tensor weight structures and t-structures on derived categories of Noetherian schemes
Umesh V Dubey, Gopinath Sahoo
We give a condition which characterises those weight structures on a derived category which come from a Thomason filtration on the underlying scheme. Weight structures satisfying o…

Compactly generated tensor t-structures on the derived category of a Noetherian scheme
Gopinath Sahoo, Umesh V. Dubey
We introduce a tensor compatibility condition for t-structures. For any Noetherian scheme , we prove that there is a one-to-one correspondence between the set of filtrations of…
