报告简介:
In this talk, we are concerned with the Hamiltonian elliptic system in dimension two involving exponential nonlinearities. 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. 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 nonlinearities have polynomial growth. It seems that it is the first attempt to obtain multi-peak semiclassical states for Hamiltonian elliptic system with exponential growth.
