Autoduality for curves of compact type
  We prove autoduality for curves of compact type and, more generally, treelike curves with planar singularities. More precisely, we produce an isomorphism between the generalized Jacobian of such a curve and the connected component of the identity of the Picard scheme of the compactified Jacobian of the curve.
