Compact Moduli of Elliptic Surfaces with a Multiple Fiber
Yongnam Lee (Korea Advanced Institute of Science and Technology)
Abstract
Motivated by Miranda and Ascher-Bejleri's works on compactification of moduli space of rational elliptic surfaces with a section, we study to construct compacti moduli space of elliptic surfaces with a multiple fiber. Particular emphasis is placed on the study of rational elliptic surfaces without section and Dolgachev surfaces. The main approach to understanding limit surfaces is Q-Gorenstein smoothing of slc surfaces. This is a joint work with Donggun Lee.
