We characterize solutions to the homogeneous parabolic p-Laplace equation $u_{t}=|\nabla u|^{2-p}\Delta_{p}u=(p-2)\Delta_{\infty}u+\Delta u$ in terms of an asymptotic mean value property. The results are connected with the analysis of tug-of-war games with noise in which the number of rounds is bounded. The value functions for these games approximate a solution to the PDE above when the parameter that controls the size of the possible steps goes to zero. 

Asymptotic mean value properties for the P-Laplacian

The purpose of this article is to obtain mean value characterizations of solutions to some nonlinear PDEs. To motivate the results we review some recent results concerning Tug-of-War games and their

We introduce a new class of strongly degenerate nonlinear parabolic PDEs ((p − 2)∆ ∞,X + ∆X )u(X,Y, t) + (m + p)(X · ∇Y u(X,Y, t) − ∂tu(X,Y, t)) = 0, (X,Y, t) ∈ R × R × R, p ∈ (1,∞), combining the

We formulate a stochastic differential game in continuous time that represents the unique viscosity solution to a terminal value problem for a parabolic partial differential equation involving the

Asymptotic mean value formulas, nonlocal space-time parabolic operators and anomalous tug-of-war games

The fractional heat operator (∂t − ∆x) s and Continuous Time Random Walks (CTRWs) are interesting and sophisticated mathematical models that can describe complex anomalous systems. In this paper, we

Tug-of-War games and the infinity Laplacian with spatial dependence

In this paper we look for PDEs that arise as limits of values of tug-of-war games when the possible movements of the game are taken in a family of sets that are not necessarily Euclidean balls. In

On the Equivalence of Viscosity Solutions and Weak Solutions for a Quasi-Linear Equation

The main result states that in both the elliptic and the parabolic case, the viscosity supersolutions coincide with the potential-theoretic supersolutions.

The infinity Laplacian, Aronsson’s equation and their generalizations

The infinity Laplace equation Δ ∞ u = 0 arose originally as a sort of Euler-Lagrange equation governing the absolute minimizer for the L ∞ variational problem of minimizing the functional ess-sup U

Tug-of-war and the infinity Laplacian

We consider a class of zero-sum two-player stochastic games called tug-of-war and use them to prove that every bounded real-valued Lipschitz function F on a subset Y of a length space X admits a

An asymptotic mean value characterization for p-harmonic functions

We characterize p-harmonic functions in terms of an asymptotic mean value property. A p-harmonic function u is a viscosity solution to Δ p u = div(|∇u| p-2 ∇u) = 0 with 1 < p ≤ ∞ in a domain Ω if and

This paper treats degenerate parabolic equations of second order $$u_t + F(\nabla u,\nabla ^2 u) = 0$$ (14.1) related to differential geometry, where ∇ stands for spatial derivatives of u =

Dynamic Programming Principle for tug-of-war games with noise

We consider a two-player zero-sum-game in a bounded open domain Ω described as follows: at a point x  ∈ Ω, Players I and II play an e -step tug-of-war game with probability α , and with probability β

We consider singular regenerate parabolic equations including the p-Laplace diffusion equation. We establish a comparison principle which is a natural extension of the paper by Ishii and Souganidis.

A deterministic‐control‐based approach to fully nonlinear parabolic and elliptic equations

We show that a broad class of fully nonlinear, second‐order parabolic or elliptic PDEs can be realized as the Hamilton‐Jacobi‐Bellman equations of deterministic two‐person games. More precisely:
