Large deviations for an obstacle problem with T-monotone operator and multiplicative noise

Abstract

In this paper, we study the large deviation principle (LDP) for obstacle problems governed by a T-monotone operator and small multiplicative stochastic reaction. Our approach relies on a combination of new sufficient condition to prove LDP by Matoussi, Sabbagh and Zhang [Appl. Math. Optim. 2021] and Lewy-Stampacchia inequalities to manage the Lagrange-multiplier associated with the obstacle.
