The desingularization of the theta divisor of a cubic threefold as a moduli space

Arend Bayer, Sjoerd Beentjes, Soheyla Feyzbakhsh +4

We show that the moduli space ${\overline{M}}_X(v)$ of Gieseker stable sheaves on a smooth cubic threefold $X$ with Chern character $v=(3,-H,-H^2/2,H^3/6)$ is smooth and of dimensi…
