报告摘要:
In this talk, we will briefly introduce the Maslov-type index for symplectic paths starting from identity and its iteration theory under periodic solution and brake orbit boundary conditions. As. Applications, we will study the minimal period problems for symmetric periodic solutions and brake orbits of nonlinear autonomous semipositive Hamiltonian systems and reversible semipositive Hamiltonian systems.
