Genus one correspondence between tropical and algebraic curves

Alessio Cela, Sae Koyama

We show that the genuinely enumerative count of algebraic elliptic curves in any toric variety agrees with the count of the corresponding well-spaced tropical curves, weighted by e…

Interpolation for rational curves with secants

Alessio Cela, Carl Lian

In arbitrary characteristic, we determine the maximum number of general points through which a rational curve of degree in passes, subject to an additional secan…

Complete quasimaps to

Alessio Cela, Carl Lian

We introduce a moduli space of ``complete quasimaps'' to . The construction, following previous work for curves on projective spaces, esse…

Fixed-domain curve counts for blow-ups of projective space

Alessio Cela, Carl Lian

We study the problem of counting pointed curves of fixed complex structure in blow-ups of projective space at general points. The geometric and virtual (Gromov-Witten) counts are f…

A Brill-Noether Theorem for (toric) surfaces

Alessio Cela, Carl Lian

The classical Brill-Noether theorem states that a map from a general curve to a projective space deforms in a family of expected dimension as long as its image does not lie in any…

Curves on Hirzebruch Surfaces and Semistability

Alessio Cela, Carl Lian

When , we show that a general pointed curve never interpolates through the expected number of points in the Hirzebruch surface , with one exception. In the ex…
