Symplectic geometry of semisimple orbits
Hassan Azad, Erik van den Ban, Indranil Biswas
We prove that any coadjoint orbit with real eigenvalues of a complex semisimple Lie group, equipped with the real part of the canonical holomorphic symplectic form, is symplectomor…
Coupled vortex equations and Moduli: Deformation theoretic Approach and Kaehler Geometry
Indranil Biswas, Georg Schumacher
We investigate differential geometric aspects of moduli spaces parametrizing solutions of coupled vortex equations over a compact Kaehler manifold X. These solutions are known to b…
Chen--Ruan cohomology of some moduli spaces
Indranil Biswas, Mainak Poddar
Let X be a compact connected Riemann surface of genus at least two. We compute the Chen--Ruan cohomology ring of the moduli space of stable PSL(2, C)--bundles of nontrivial second…
On the stratified vector bundles
Indranil Biswas
The stratified vector bundles on a smooth variety defined over an algebraically closed field form a neutral Tannakian category over . We investigate the affine group--scheme…
Parabolic principal Higgs bundles
Indranil Biswas
In ``Ramified G-bundles as parabolic bundles'' (J. Ramanujan Math. Soc. (2003) Vol. 18) with Balaji and Nagaraj we introduced the ramified principal bundles. The aim here is to def…
Generalization of a criterion for semistable vector bundles
Indranil Biswas, Georg Hein
It is known that a vector bundle E on a smooth projective curve Y defined over an algebraically closed field is semistable if and only if there is a vector bundle F on Y such that…
