The $C^{0,1}$ It\^o-Ventzell formula for weak Dirichlet processes

Probability 2025-04-10 v4

Abstract

This paper proves an extension of the It\^o-Ventzell formula that applies to stochastic flows in C0,1C^{0,1} for continuous weak Dirichlet processes. We apply this theorem, for example, to give a representation result for strong solutions of time-dependent elliptic SPDEs, to derive formulas for quadratic variations, and to relax assumptions in a financial mathematics context.
