Let $${\mathcal{M}_g }$$ be the moduli space of smooth complex projective curves of genus g. Here we prove that the subset of $${\mathcal{M}_g }$$ formed by all curves for which some Brill-Noether locus has dimension larger than the expected one has codimension at least two in $${\mathcal{M}_g }$$ . As an application we show that if $${X \in \mathcal{M}_g }$$ is defined over...
For a smooth projective irreducible algebraic curve C of odd gonality, the maximal possible dimension of the variety of special linear systems W dr (C) is d-3r by a result of M. Coppens et al. Furthermore it is known that if the maximum dimension of W(C) for a curve C of odd gonality is attained then C is of very special type of curves by the recent progress made by G. Martens. The purpose of this...
