Ampleness of intersections of translates of theta divisors in an abelian fourfold
O. Debarre, E. Izadi
We prove that the cotangent bundle of a complete intersection of two general translates of the theta divisor of the jacobian of a general curve of genus 4 is ample. From this the s…

Deforming curves in jacobians to non-jacobians II: curves in ,
E. Izadi
We introduce deformation theoretic methods for determining when a curve in a non-hyperelliptic jacobian will deform with to a non-jacobian. We apply these methods to…
