OpenAI reports uniform interior C¹,α bounds for infinity-harmonic functions

For each integer d≥3 there are αd∈(0,1/3] and Cd<∞ such that every bounded infinity-harmonic function on the unit ball has gradient supremum and αd-Hölder seminorm on the half ball bounded by Cd times its oscillation on the unit ball.

Understanding the problem

Read the background

For each integer d≥3 there are αd∈(0,1/3] and Cd<∞ such that every bounded infinity-harmonic function on the unit ball has gradient supremum and αd-Hölder seminorm on the half ball bounded by Cd times its oscillation on the unit ball.

Why it matters

If correct, upgrades pointwise differentiability to uniform local C¹,α regularity in every higher dimension.

What counts as progress

Do infinity-harmonic functions in dimensions at least three have uniform interior Hölder-continuous gradients?
