报告题目:Some new results on normalized solutions of Schrodinger equations and systems 

报告摘要:

  We introduce some new results on normalized solutions, especially for normalized solutions of mass subcritical Schrodinger equations in exterior domains; normalized solutions to p-Laplacian equations with combined nonlinearities; normalized solutions to Schrodinger systems etc.

报告题目: Single-peak and multi-peak solutions for Hamiltonian elliptic systems in dimension two

报告摘要:

  This paper is concerned with the Hamiltonian elliptic system in dimension two,where the potential has local minimum points, and the nonlinearities are assumed to be of exponential growth in the sense of Trudinger-Moser inequality. When the potential admits one or several local strict minimum points, we show the existence and concentration of single-peak and multi-peak semiclassical states respectively, as well as strong convergence and exponential decay. In addition, positivity of solutions and uniqueness of local maximum points of solutions are also studied. Our theorems extend the results of Ramos and Tavares [Calc. Var. 31 (2008) 1-25], where the nonlinearity have polynomial growth. It seems that it is the first attempt to obtain multi-peak semiclassical states for Hamiltonian elliptic system with exponential growth. This is a joint work with Minbo Yang, Jianjun Zhang and Xuexiu Zhong.
