摘要

This paper is devoted to the study of the convergence of the Lax-Oleinik semigroup associated with reversible Hamiltonians H(x, p) on R-n. We provide a necessary and sufficient condition for the convergence of the semigroup. We also give an example to show that for irreversible Hamiltonians on R-n, even if the Hamiltonian is integrable and the initial data is Lipschitz continuous and bounded, the corresponding Lax-Oleinik semigroup may not converge.
