The harmonic mean formula for random processes
Krzysztof Bisewski, Enkelejd Hashorva, Georgiy Shevchenko · 2021-06-22 · via math.PR updates on arXiv.org

Motivated by the harmonic mean formula in [1], we investigate the relation between the sojourn time and supremum of a random process $X(t),t\in \mathbb{R}^d$ and extend the harmonic mean formula for general stochastically continuous $X$. We discuss two applications concerning the continuity of distribution of supremum of $X$ and representations of classical Pickands constants.
