Extension of structure groups of principal bundles in positive characteristic
Fabrizio Coiai, Yogish I. Holla
In this article we study the behaviour of semistable principal -bundles over a smooth projective variety under the extension of structure groups in positive characteristic.…
Maximal subbundles and Gromov invariants
Yogish I. Holla
In this article we explicitly compute the number of maximal subbundles of rank of a generically stable bundle of rank and degree over a smooth projective curve of g…
Parabolic reductions of principal bundles
Yogish I. Holla
In this paper we describe the structure of the space of parabolic reductions, and their compactifications, of principal -bundles over a smooth projective curve over an algebraic…
Topology of Quadric Bundles
Yogish I. Holla, Nitin Nitsure
This paper begins with a description of cohomological invariants of non-degenerate quadric bundles, in terms of the cohomology rings of the classifying spaces of the general orthog…
Characteristic Classes for GO(2n,C)
Yogish I. Holla, Nitin Nitsure
The complex Lie group GO(2n,C) by definition consists of all complex matrices A of size 2n, such that A times transpose(A) is a non-zero scalar. In this paper we determine explicit…
