Irreducibility of a universal Prym-Brill-Noether locus

Andrei Bud

For genus $g = \frac{r ( r + 1 )}{2} + 1$ , we prove that via the forgetful map, the universal Prym-Brill-Noether locus $R_{g}^{r}$ has a unique irreducible component dominating the…

The birational geometry of $R_{g, 2}$ and Prym-canonical divisorial strata

Andrei Bud

We prove that the moduli space of double covers ramified at two points $R_{g, 2}$ is uniruled for $3 \leq g \leq 6$ and of general type for $g \geq 16$ . Furthermore, we consi…

A Hurwitz divisor on the Moduli of Prym curves

Andrei Bud

For genus $g = 2 i \geq 4$ and the length $g - 1$ partition $μ = (4, 2, \dots, 2, - 2, \dots, - 2)$ of 0, we compute the first coefficients of the class of $D (μ)$ in $\mathrm{Pic}_\ma…
