报告摘要：

We consider existence of multiple solutions to a class of parameter-dependent quasilinear elliptic equations and investigate sign properties of these solutions. Six solutions with sign properties are obtained by using a perturbation method incorporated into the invariant set arguments. We also obtain more and more solutions as the parameter gets larger and larger, based on a non-smooth critical point theory. It is expected that those solutions are sign-changing. For more constrained nonlinearities, we prove existence of more and more sign-changing solutions as the parameter tends to infinity.
