Interpolation, Prekopa and Brunn-Minkowski for -subharmonicity
arXiv:2206.00576
Abstract
We extend Prekopa's Theorem and the Brunn-Minkowski Theorem from convexity to -subharmonicity. We apply this to the interpolation problem of convex functions and convex sets introducing a new notion of "harmonic interpolation" that we view as a generalization of Minkowski-addition.
