[HTML][HTML] Random Lax–Oleinik semigroups for Hamilton–Jacobi systems

A Davini, A Siconolfi, M Zavidovique - Journal de Mathématiques Pures et …, 2018 - Elsevier
Following the random approach of [1], we define a Lax–Oleinik formula adapted to evolutive
weakly coupled systems of Hamilton–Jacobi equations. It is reminiscent of the
corresponding scalar formula, with the relevant difference that it has a stochastic character
since it involves, loosely speaking, random switchings between the various associated
Lagrangians. We prove that the related value functions are viscosity solutions to the system,
and establish existence of minimal random curves under fairly general hypotheses. Adding …
