Abstract

In this paper, we explore the inflectionary behavior of linear series on superelliptic curves XX over fields of arbitrary characteristic. Here we give a precise description of the inflection of linear series over the ramification locus of the superelliptic projection; and we initiate a study of those inflectionary varieties that parameterize the inflection points of linear series on XX supported away from the superelliptic ramification locus that is predicated on the behavior of their Newton polytopes.
