In the past few decades, compactifying the moduli spaces of projective K3 surfaces has attracted a lot attentions from several perspectives including Hodge theory, birational geometry, K¨ahler-Einstein geometry and mirror symmetry. It turns out we have the Baily-Borel compactification, Koll´ar-Shepherd-BarronAlexeev (KSBA) compactification, K-stability compactification etc. It is a natural question to ask what is the relation of these compactifications of different flavors. In this talk, we will explain how the Hassett-Keel-Looijenga (HKL) program try to put these compactifications into the framework of wall-crossing. This is based on joint work with Greer-Laza-Li-Tian.
