Title: Uniform Interior $C{}{1,{}alpha}$ Estimates for Infinity-Harmonic Functions.

Abstract: We prove a uniform interior $C{}{1,{}alpha_d}$ estimate for bounded infinity-harmonic functions in every dimension d ≥ 3. For some ${}alpha_d{}in(0,1/3]$ depending only on the dimension, the gradient's supremum norm and αd-Hölder seminorm on B1/2 are bounded by a dimension-dependent constant times the oscillation on B1. The exponent is not explicit, and no endpoint or boundary regularity claim is made. In particular, infinity-harmonic functions are locally C1 on every open subset of ℝd, for d ≥ 3.
