题 目：Pairs of sign-changing solutions for sublinear elliptic equations with the Neumann boundary condition
时 间：11.04 (星期三) , 16:00-17:00
地 点：数学院南楼N818室
Abstract :We consider the Neumann problem for a class of sublinear elliptic equations in a bounded domain. By an variant of Clark theorem, we obtain the existence and multiplicity results of sign-changing solutions. The same arguments can be used to discuss second Hamiltonian systems, etc.
