The degree-2 Abel--Jacobi map for nodal curves - I

Marco Pacini

Published 2013-04-18Version 1

Let $f\col\C\ra B$ be a regular local smoothing of a nodal curve. In this paper, we find a modular description of the Abel--N\'eron map having values in Esteves's fine compactified Jacobian and extending the degree-2 Abel--Jacobi map of the generic fiber of $f$
