Degenerations of generalized Kummer varieties
Lars H. Halle, Klaus Hulek, Ziyu Zhang
We present a method to construct explicit degenerations of higher-dimensional generalized Kummer varieties. We start with a simple degeneration of abelian sur…

Base change conductors through intersection theory and quotient singularities
Dennis Eriksson, Lars Halvard Halle, Johannes Nicaise
We perform a systematic study of the base change conductor for Jacobians. Through the lens of intersection theory and Deligne's Riemann-Roch theorem, we present novel computational…
