A Note on primitive pairs for graded Lie algebras

Tamanna Chatterjee

We develop a theory of primitive pairs for $Z$ -graded Lie algebras when the sheaves have coefficients in a field $k$ of positive characteristic, providing a graded ana…

Fourier transform on graded Lie algebras

Tamanna Chatterjee

In this paper we study the Fourier transform on graded Lie algebras. Let $G$ be a complex, connected, reductive, algebraic group, and $I ¨ : C^{\times} \to G$ be a fixed cochar…

Equivariant sheaves for classical groups acting on Grassmannians

Pramod N. Achar, Tamanna Chatterjee

Let $V$ be a finite-dimensional complex vector space. Assume that $V$ is a direct sum of subspaces each of which is equipped with a nondegenerate symmetric or skew-symmetric biline…
