Rough path: Applications, Overview & Motivation

In stochastic analysis, a rough path is a generalization of the classical notion of a smooth path. It extends calculus and differential equation theory to handle irregular signals—paths that are too rough for traditional analysis, such as a Wiener process. This makes it possible to define and solve controlled differential equations of the form d y t = f…
