Abstract:

Minimal measure is introduced for positive definite Lagrangian system to study the dynamics. For autonomous system, the support lies in the level set of the Hamiltonian not below the Mañé critical value. We find that, for classical system, there also exists some minimal measure on the level set below the Mañé critical value.
