Fine compactified moduli of enriched structures on stable curves
Owen Biesel, David Holmes
Enriched structures on stable curves over fields were defined by Maino in the late 1990s, and have played an important role in the study of limit linear series and degenerating jac…

Néron models and the height jump divisor
Owen Biesel, David Holmes, Robin de Jong
We define an algebraic analogue, in the case of jacobians of curves, of the height jump divisor introduced recently by R. Hain. We give explicit combinatorial formulae for the heig…
