Tóm tắt: The objects of the talk are the curves C over an algebraically closed field of positive characteristic, which are equipped with an action of a finite group scheme G. Then G does not necessarily act on the smooth projective model of C, but there is a unique "G-normal" projective model X. The talk will discuss the G-equivariant vector bundles on X, and extend some fundamental results about vector bundles on smooth curves to this singular setting.
