On the Aleksandrov-Bakelman-Pucci estimate for the infinity Laplacian

We prove $L^\infty$ bounds and estimates of the modulus of continuity of solutions to the Poisson problem for the normalized infinity and $p$-Laplacian, namely $-Δ_p^N u=f\qquad\text{for $n<p\leq\infty$.}$ We are able to provide a stable family of results depending continuously on the parameter $p$. We also prove the failure of the classical Alexandrov-Bakelman-Pucci estimate for the normalized infinity Laplacian and propose alternate estimates.
