报告人:李奎教授(郑州大学)

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 critical hyperbolic 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.

时间:上午11:00-12:00

报告人:罗海军博士(湖南大学)

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.

午餐、休息12:00-下午2:30

4.

时间:下午2:30-3:30

报告人:刘海东教授(嘉兴学院)

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.

5.

时间:下午3:30-4:30

报告人:孙冬冬教授(齐鲁师范大学)

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.
