The non-properness of the functor of F-trivial bundles
Vikram B. Mehta, S. Subramanian
We study the properness of the functor of -trivial bundles by relating it to the base change question for the fundamental group scheme of Nori.
On the Picard group of moduli spaces
Kirti Joshi, V. B. Mehta
We study the Picard groups of moduli spaces in positive characteristics and we give a "-adic" proof that the Picard group of moduli of vector bundles of fixed determinant is iso…
Vector bundles with Theta divisors I: Bundles on Castelnuovo curves
Kirti Joshi, V. B. Mehta
In this paper we show that semistable vector bundles on a Castelnuovo curve of genus g >= 2 have theta divisors. As a corollary, we deduce that semistable vector bundles on a smoot…
Restriction theorems for homogeneous bundles
V. B. Mehta, V. Trivedi
We prove that for an irreducible representation , the associated homogeneous -vector bundle is strongly semistable when restricted to any smoot…
Frobenius morphisms over Z/p^2 and Bott vanishing
A. Buch, J. F. Thomsen, N. Lauritzen +1
Let be a smooth projective algebraic variety over , which has a flat lift to a scheme over . If the absolute Frobenius morphism on lifts to a morphism…
On a Grauert-Riemenschneider vanishing theorem for Frobenius split varieties in characteristic p
V. B. Mehta, Wilberd van der Kallen
This paper is about sheaf cohomology for varieties (schemes) in characteristic . We assume the presence of a Frobenius splitting. (See V.B. Mehta and A. Ramanathan, Frobenius…
