       Abstract：In this talk I will introduce some linking theorems and mountain pass type results for dynamical systems in terms of local semiflows on complete metric spaces. These results provide an alternative approach for finding nonempty compact invariant sets without using the Conley index. They can also be applied to variational problems of elliptic equations without verifying the classical P.S. Condition.Examples will be given to illustrate how to use the theoretical results to solve problems of PDEs.
