摘要

Complexiﬁed complement of hyperplane arrangements are one of the most classical examples of study in singularity theory and algebraic geometry, while its symplectic properties are largely under exploration. In this talk, I’ll present our recent progress toward understanding symplectic geometry of hyperplane arrangements, which is connected to torus-equivariant topology of toric hyperKahler varieties. TTis is based on the recent joint work with S. Lee, Y. Li and C. Y. Mak and work in preparation with S. Ganatra, W. Li and P. Zhou.
