Entropy penalization methods for Hamilton–Jacobi equations

Abstract

In this paper we present a new entropy penalization problem and we discuss its relations with approximate solutions of Hamilton–Jacobi equations, the convergence of associated discrete schemes, as well as several applications, such as: a generalization of the Hopf–Cole transformation which converts non-linear Hamilton–Jacobi equations into linear evolution equations, the study of fixed point problems, approximation of certain linear evolution equations, and the construction of entropy penalized Mather measures.
