Infinity-harmonic functions and inverse mean curvature flow clusters

What the math gives to ML

The paper develops a concrete limiting principle for functions that minimize worst-case gradient magnitude: in two dimensions, p-harmonic duality converges to the infinity-Laplacian equation and yields highly structured level-set geometry. The transferable asset is not the inverse-mean-curvature-flow machinery itself, which is difficult to use in generic networks, but the dual rotated-gradient constraint and the absolute-minimizer interpretation of infinity-harmonic functions. A practical use is a two-output neural coordinate or implicit-field head trained with an annealed p-harmonic/conjugacy loss, encouraging bounded local sensitivity while preserving a geometrically coherent dual field.
