On the projective structures given by theta

Indranil Biswas, Luca Vai

Given a compact Riemann surface , the line in orthogonal to the sections vanishing at produces a natural projective structure on . We investigate the pr…

Holomorphic Lie algebroid connections over rationally connected varieties

Indranil Biswas, Anoop Singh

Take a holomorphic Lie algebroid over a rationally connected smooth complex projective variety . We show that, under certain conditions, a vector bundle over ad…

Induced Representations on Character Varieties of Surfaces

Indranil Biswas, Jacques Hurtubise, Lisa C. Jeffrey +1

We show that a Frobenius reciprocity map on character varieties of surfaces is a Poisson embedding.

Poisson structure on character varieties. II

Indranil Biswas, Lisa C. Jeffrey

Let G be a complex reductive group and D a finite subset of a compact Riemann surface X. It was shown in [BJ] that the moduli space of G-characters of the complement of D in X has…
