Birational Geometry of Quot Schemes on smooth projective curves via Stable Pairs
Chandranandan Gangopadhyay, Atsushi Ito
Let be a smooth projective curve of genus over , and let be a vector bundle on . We investigate the birational geometry of the Quot scheme ${\rm…
Direct image and pullback of Parabolic vector bundles
Indranil Biswas, Chandranandan Gangopadhyay
Niels Borne established a natural correspondence between the parabolic vector bundles on curves and vector bundles on root stacks. The notions of direct image of parabolic vector b…
Some recent results on the punctual Quot schemes
Indranil Biswas, Chandranandan Gangopadhyay, Ronnie Sebastian
Let be a smooth projective curve defined over the field of complex numbers. Let be a vector bundle on , and fix an integer . Let $\mc Q:={\rm Quot}(E,d)$ b…
Infinitesimal deformations of some quot schemes, II
Indranil Biswas, Chandranandan Gangopadhyay, Ronnie Sebastian
Let be an irreducible smooth complex projective curve of genus , with . Let be a vector bundle on of rank , with . Let $\mc Q:=\mc…
Equivariant vector bundles on complexity-one T-varieties and Bruhat-Tits buildings
Jyoti Dasgupta, Chandranandan Gangopadhyay, Kiumars Kaveh +1
We give a combinatorial classification of torus equivariant vector bundles on a (normal) projective T-variety of complexity-one. This extends the classification of equivariant line…
Nef and Effective cones of some Quot Schemes
Chandranandan Gangopadhyay, Ronnie Sebastian
Let be a smooth projective curve over of genus (respectively, ). Fix integers such that , (respectively,…
