Universal Néron models for curves with marked points

Abstract

We consider the problem of constructing universal Néron models for families of curves with sections. By applying a construction of the author of universal compactified Jacobians over the moduli stack of reduced curves with markings and a result by J. Kass, we get a positive answer for smooth families of curves with planar singularities over Dedekind schemes.

Minor modifications. To appear at the Bollettino dell'Unione Matematica Italiana
