The non-properness of the functor of F-trivial bundles
We study the properness of the functor of $F$-trivial bundles by relating it to the base change question for the fundamental group scheme of Nori.

Finiteness of the number of compatibly-split subvarieties
We show that for a Frobenius split variety, there are only finitely many closed subvarieties which are compatibly-split.

Some Remarks on the Local Fundamental Group Scheme
We define the local fundamental group scheme, defined by the F-trivial vector bundles, and give necessary and sufficient conditions for it to base change.

Moduli of Principal Bundles in Positive Characteristic
In this paper we construct the moduli of semistable principal bundles with structure group a semisimple group, over nonsingular curves in positive characteristic, with good bounds on the prime.
