Frobenius morphism and vector bundles



Let X be a smooth projective variety over an algebraically closed field of positive characteristic. Let F be the relative Frobenius morphism of X. In this talk, I will discuss the behaviour of semistable bundles under the operations F* and F*. The stability of sheaves of locally closed forms and exact forms will also be discussed.
