Generalized Hasse-Witt invariants and unramified Galois extensions of an algebraic function field
In this paper, we give a certain generalization of the ).Let $K$ be an algebraic function field with an algebraically closed constant field $k$ of characteristic $p>0$, and $g$ be its genus.Let $M$ be the maximum unramified Galois extension of $K$ .Let $\Delta_{g}$ be the group generated by $2g$ elements …
