New examples of twisted Brill-Noether loci I
arXiv:2212.05573
Abstract
Our purpose in this paper is to construct new examples of twisted Brill-Noether loci on curves of genus . 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.
