Maximum principle for quasilinear stochastic PDEs with obstacle

چکیده
We prove a maximum principle for local solutions of quasilinear stochastic PDEs with obstacle (in short OSPDE). The proofs are based on a version of Itô’s formula and estimates for the positive part of a local solution which is non-positive on the lateral boundary. Our method is based on a version of Moser’s iteration scheme developed first by Aronson and Serrin [2] in the context of non-linear parabolic PDEs and recently adapted in the context of quasilinear SPDEs in [5, 7].

THE OBSTACLE PROBLEM FOR QUASILINEAR STOCHASTIC PDES: ANALYTICAL APPROACH By Laurent DENIS
Abstract: We prove an existence and uniqueness result for quasilinear Stochastic PDEs with obstacle (OSPDE in short). Our method is based on analytical technics coming from the parabolic potential theory. The solution is expressed as a pair (u, ν) where u is a predictable continuous process which takes values in a proper Sobolev space and ν is a random regular measure satisfying minimal Skohoro...
متن کاملStochastic homogenization of quasilinear PDEs with a spatial degeneracy
We investigate stochastic homogenization for some degenerate quasilinear parabolic PDEs. The underlying nonlinear operator degenerates along the space variable, uniformly in the nonlinear term: the degeneracy points correspond to the degeneracy points of a reference diffusion operator on the random medium. Assuming that this reference diffusion operator is ergodic, we can prove the homogenizati...
متن کاملProbabilistic Interpretation of a System of Quasilinear Parabolic Pdes
Using a forward– backward stochastic differential equations (FBSDE) associated to a transmutation process driven by a finite sequence of Poisson processes, we obtain a probabilistic interpretation for a non-degenerate system of quasilinear parabolic partial differential equations (PDEs). The novetly is that the linear second order differential operator is different on each line of the system.
متن کاملMaximum Principle for State - Constrained Optimal
In this paper, the authors study an optimal control problem for quasilinear elliptic PDEs with pointwise state constraints. Weak and strong optimality conditions of Pontryagin maximum principle type are derived. In proving these results, we penalized the state constraints and respectively use the Ekeland variational principle and an exact penalization method. In this paper, our aim is to prove ...
متن کاملStochastic maximum principle for optimal control of SPDEs
In this note, we give the stochastic maximum principle for optimal control of stochastic PDEs in the general case (when the control domain need not be convex and the diffusion coefficient can contain a control variable).
