Non-degeneracy of Stochastic Line Integrals

Probability 2022-02-08 v1

Abstract

We derive quantitative criteria for the existence of density for stochastic line integrals and iterated line integrals along solutions of hypoelliptic differential equations driven by fractional Brownian motion. As an application, we also study the signature uniqueness problem for these rough differential equations.
