Harmonically lifting linear series from curves to K3 surfaces

Richard Haburcak

We investigate the question of which Brill--Noether special linear series on a curve on a K3 surface lift to the surface. Work of Reid, Donagi--Morrison, Green--Lazarsfeld, Lelli-C…

Pointed Hurwitz--Brill--Noether theory

Andrei Bud, Richard Haburcak

We study the geometry of Hurwitz--Brill--Noether spaces with vanishing conditions at a totally ramified point. Degeneration to a curve with an elliptic tail simplifies the combinat…

Brill--Noether loci in genus

Richard Haburcak

A refined Brill--Noether theory seeks to determine which linear series are admitted by a ``general'' curve in a particular Brill--Noether locus. However, as Brill--Noether loci are…

Some reducible and irreducible Brill-Noether loci

Richard Haburcak, Montserrat Teixidor i Bigas

We investigate limit linear series on chains of elliptic curves, giving a simple proof of a conjecture of Farkas stating the existence of curves with a theta-characteristic with a…

Distinguishing Brill-Noether loci

Asher Auel, Richard Haburcak, Andreas Leopold Knutsen

We construct curves carrying certain special linear series and not others, showing many non-containments between Brill-Noether loci in the moduli space of curves. In particular, we…

Maximal Brill-Noether loci via degenerations and double covers

Andrei Bud, Richard Haburcak

Using limit linear series on chains of curves, we show that closures of certain Brill--Noether loci contain a product of pointed Brill--Noether loci of small codimension. As a resu…

Maximal Brill--Noether loci via the gonality stratification

Asher Auel, Richard Haburcak, Hannah Larson

We study the restriction of Brill-Noether loci to the gonality stratification of the moduli space of curves of fixed genus. As an application, we give new proofs that Brill-Noether…

Curves on Brill-Noether special K3 surfaces

Richard Haburcak

Mukai showed that projective models of Brill-Noether general polarized K3 surfaces of genus and are obtained as linear sections of projective homogeneous varieties, and…

Maximal Brill-Noether loci via K3 surfaces

Asher Auel, Richard Haburcak

We explain a strategy for distinguishing Brill-Noether loci in the moduli space of curves by studying the lifting of linear systems on curves in polarized K3 surfaces, which motiva…
