We provide a universal approach to the moduli of Jun Li's expanded pairs and expanded degenerations. This enables us to prove algebraicity results, compare with Li's approach and with the approach of Graber and Vakil, and generalize to the twisted expansions used by Abramovich and Fantechi as a basis for orbifold techniques in degeneration formulas.

Abstract

We provide a universal approach to the moduli of Jun Li's expanded pairs and expanded degenerations. This enables us to prove algebraicity results, compare with Li's approach and with the approach of Graber and Vakil, and generalize to the twisted expansions used by Abramovich and Fantechi as a basis for orbifold techniques in degeneration formulas.
