Gradient and Lipschitz estimates for tug-of-war type games
Amal Attouchi, Hannes Luiro, Mikko Parviainen
We define a random step size tug-of-war game, and show that the gradient of a value function exists almost everywhere. We also prove that the gradients of value functions are unifo…
Asymptotic Lipschitz regularity for tug-of-war games with varying probabilities
Ángel Arroyo, Hannes Luiro, Mikko Parviainen +1
We prove an asymptotic Lipschitz estimate for value functions of tug-of-war games with varying probabilities defined in . The method of the proof is based on…
The Variation of the Fractional Maximal Function of a Radial Function
Hannes Luiro, José Madrid
In this paper we study the regularity of the non-centered fractional maximal operator . As the main result, we prove that there exists such that if and $f…
The variation of the maximal function of a radial function
Hannes Luiro
We study the problem concerning the variation of the Hardy-Littlewood maximal function in higher dimensions. As the main result, we prove that the variation of the non-centered Har…
Gradient walk and -harmonic functions
Hannes Luiro, Mikko Parviainen
We consider a class of stochastic processes and establish its connection to -harmonic functions. In particular, we obtain stochastic approximations that converge uniformly to a…
Regularity for nonlinear stochastic games
Hannes Luiro, Mikko Parviainen
We establish regularity for functions satisfying a dynamic programming equation, which may arise for example from stochastic games or discretization schemes. Our results can also b…
