Naturality of Abel maps
Lucia Caporaso
We give a combinatorial characterization of nodal curves admitting a natural d-th Abel map to their Picard scheme, for any positive integer d. "Natural" here means compatible with…

On Abel maps of stable curves
Lucia Caporaso, Eduardo Esteves
We construct Abel maps for a stable curve . Namely, for each one-parameter deformation of with regular total space, and every integer , we construct by specialization a…
