Query: Frobenius Stratification of Moduli Spaces of Rank $3$ Vector Bundles in
  Characteristic $3$, I   Let $X$ be a smooth projective curve of genus $g\geq 2$ over an algebraically
closed field $k$ of characteristic $p>0$, $F_X:X\rightarrow X$ the absolute
Frobenius morphism. Let $\M^s_X(r,d)$ be the moduli space of stable vector
bundles of rank $r$ and degree $d$ on $X$. We study the Frobenius
stratification of $\M^s_X(3,0)$ in terms of Harder-Narasimhan polygons of
Frobenius pull backs of stable vector bundles and obtain the irreducibility and
dimension of each non-empty Frobenius stratum in the case $(p,g)=(3,2)$.
