On the ring of unipotent vector bundles on elliptic curves in positive characteristics
Stefan Schroeer
Using Fourier-Mukai transformations, we prove some results about the ring of unipotent vector bundles on elliptic curves in positive characteristics. This ring was determined by At…

On fibrations whose geometric fibers are nonreduced
Stefan Schroeer
We give a bound on embedding dimensions of geometric generic fibers in terms of the dimension of the base, for fibrations in positive characteristic. This generalizes the well-know…
