Compactified Jacobians of Néron type cover


We characterize stable curves XX whose compactified degree-dd Jacobian is of Néron type. This means the following: for any one-parameter regular smoothing of XX, the special fiber of the Néron model of the Jacobian is isomorphic to a dense open subset of the degree-dd compactified Jacobian of XX. It is well known that compactified Jacobians of Néron type have the best modular properties, and that they are endowed with a mapping property useful for applications.
