New examples of twisted Brill-Noether loci I
Published 11 Dec 2022 in math.AG | (2212.05573v3)
Abstract: Our purpose in this paper is to construct new examples of twisted Brill-Noether loci on curves of genus $g\ge2$. Many of these examples have negative expected dimension. We deduce also the existence of a new region in the Brill-Noether map, whose points support non-empty standard Brill-Noether loci.
