Strongly Semistable Bundles on a Curve over a finite field
S. Subramanian
We show that a principal G bundle on a smooth projective curve over a finite field is strongly semistable if and only if it is defined by a representation of the fundamental group…

Vikram B. Mehta, S. Subramanian
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.
