摘要

Let $P_d$ be the moduli space of pairs $(X,C)$ where $X$ is a smooth del Pezzo surface and $C\sim -2K_X$ is a smooth curve. In this talk we will introduce compactifications for the moduli space $P_d$ from three perspectives: GIT, Hodge theory and K-stability. The precise relationships of these compactifications will be discussed.
