SIMIS Seminar on Geometric Analysis and PDEs: Some long time existence and convergence results on hypersymplectic flow

报告人： 姚成建（上海科技大学）

摘要： Hypersymplectic structure on a 4-manifold is a triple of symplectic forms such that any nontrivial linear combination of them is symplectic. The hypersymplectic flow is a natural geometric flow designed with the goal of deforming one given hypersymplectic structure in its cohomology class to a hyperKahler structure. This flow also has close relation with Bryant’s G_2 Laplacian flow on 7-manifold. In this talk, we will present some long time existence and convergence results about the flow, and in particular one recent convergence result on 4-torus proved together with Joel Fine and Weiyong He.
