Moduli spaces of $G$-constellations on $\mathbb{C}^2$ and their birational geometry
[ Abstract ]
Let $G$ be a finite subgroup of $GL_2(\mathbb{C})$. Ishii conjectured that a resolution of $\mathbb{C}^2/G$ is dominated by the maximal resolution of the quotient pair if and only if it is isomorphic to a moduli space of King-stable $G$-constellations. After reviewing the background, I will outline a proof of this conjecture. I will then present a complementary result on wall-crossing for moduli spaces of Bridgeland-stable $G$-constellations.
