报告题目:Sign-changingsolutions of nonlinear problems involving the fractional p-laplace operator
摘 要:In this talk, I willreport some recent results on the sign-changing
solutions of nonlinearproblems involving the fractional p-laplace operator. We will use twodifferential methods to obtain sign-changing solutions with high energy andleast energy respectively. In fact, by applying the method of invariantsets of descending flow and minimax theory, we obtain the existence andmultiplicity of sign-changing solutions with high energy. Inaddition, by using the Nehari manifold method, we prove thatthe problem admits one least energy sign-changing solution.
