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…

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…
