We develop the rough path counterpart of It stochastic integration and differential equations driven by general semimartingales. Weborem, asserts that a rough path has a unique lifting to the full tensor algebra which has the same regularity. In particular, a rough path can also be rep-resented by a formal tensor series of “generalized iterated integrals” as in the bounded variation case. In the rough path literature, such representation is

WebThe geometric theory of rough paths is restricted to drivers which respect the usual chain rule of smooth paths. A meaningful generalisation of the theory was provided by Gubinelli's notion of branched rough paths [29].
