\n\tAbstract: This is a talk on an introduction of various symplectic \ninvariants and its related Hamiltonian dynamics questions. First, I will\n do a quick summary of current well-known invariants including spectral \ninvariant, symplectic capacities, boundary depth, symplectic \nquasi-state, etc., with their related questions in Hofer geometry. Then I\n will demonstrate a relatively uniform method with keyword, \nperturbation, that how these invariants can be used to answer some of \nthese questions. Finally, I will mention my own work on a new \nperturbation technique to reprove many old results and also pose some \nnew questions. Some background on Hamiltonian Floer theory are \nrequired. \n<\/div>\n
