报告题目:The threshold theorem for energy critical hyperbolic Yang-Mills equation 摘要:In this talk, I will give an overview of the proof of Oh and Tataru’s Threshold Theorem for the energy criticalhyperbolic Yang-Mills equation. It asserts that the (4+1) dimensional Yang-Mills system is globally well-posed in the caloric gauge for all topologically trivial initial data below twice the ground state energy.

报告题目: The Yang–Mills heat flow and the caloric gauge
摘要:In this talk, we are first concerned with the study of global solutions for the Yang–Mills heat flow, and establish sharp criteria for global existence and asymptotic convergence to a flat connection for this system. Our second goal is to use the Yang–Mills heat flow in order to define the caloric gauge. And in this gauge, we can arrive at a good formulation of the hyperbolic Yang–Mills equation, which will play a major role in the proofs of the Threshold Theorem and the Dichotomy Theorem for the hyperbolic Yang–Mills equation.

题目:Existence and multiplicity results for a quasilinear Schrodinger equation
摘要:We consider the quasilinear Schrodinger equation
where V is a potential function and N≥3. Under some natural assumptions on V and h, we prove some existence and multiplicity results. Our method relies on Jeanjean's monotonicity trick, decomposition of bounded Palais-Smale sequence, symmetric mountain pass theorem and Pohozaev identity. This talk is based on joint works with Dr. Yongtao Jing, Prof. Zhaoli Liu and Prof. Leiga Zhao.

题目:Recent results on Schr?dinger-Kirchhoff equations
摘要:In this talk, we will give a list of results in recent years on Schr?dinger-Kirchhoff equations and we then show our recent results, which contain uniqueness and multiplicity results, results of equations with competing potentials and vanishing potentials, etc.
