報告摘要：
Hypersymplectic structure on a 4-manifold is a triple of symplectic forms such that any nontrivial linear combination is symplectic. The hypersymplectic flow is a natural geometric flow designed to deform one given hypersymplectic structure in its cohomology class isotopically to a hyperKahler structure. In this talk, we will review the very basics of hypersymplectic structure and the flow, and then present some long time existence and convergence results about the flow based on joint works with Joel Fine and Weiyong He.
