摘要：

Over the complex numbers, Plucker's formula computes the number of inflection points of a linear series of fixed degree and projective dimension on an algebraic curve of fixed genus. Here, we explore the geometric meaning of a natural analog of Plucker's formula and its constituent local indices in A(1)-homotopy theory for certain linear series on hyperelliptic curves defined over an arbitrary field.
