An upper bound on the generic degree of the generalized Verschiebung for rank two stable bundles
Yuichiro Hoshi, Yasuhiro Wakabayashi
In the present paper, we give an upper bound for the generic degree of the generalized Verschiebung between the moduli spaces of rank two stable bundles with trivial determinant.
