Lyons’ rough path analysis has provided new insights in the analysis of stochastic differential equations and stochastic partial differential equations, such as the kpz equation.

Rough paths were born as such integrators, with the rough integral of controlled integrands, defined in exercise 13, in the role of itô integrals. What links these two notions of integrals is the following fudamental fact. Brownian motion has a natural lift into a hölder p-rough path,for any 2p3, called the brownian rough path.

It works like this: initial rough machining is performed first, then the resulting form is used as the new stock for a subsequent roughing tool path. Roughing can then proceed according to a different method—parallel, spiral, stock-spiral, what have you—with just the new stock.

This course is a introduction to the theory of rough paths, controlled paths and to recent developments in the analysis of singular spdes. Rough paths were introduced by lyons in the '90s as the right topology in which the map from a stochastic process to the solution of a stochastic differential equation driven by this process become continuous. This continuity, which is not present in ito's theory of integration, allows to obtain quite directly a lot of results on the stability and fine.
The essence of rough path theory is to require a path to satisfy the p-variation type estimate not only for the path itself but also the iterated integrals.

We prove that the theory of rough paths, which is used to define path-wise integrals and path-wise differential equations, can be used with continuous semi-martingales. Moreover, we show that the conditions ut and ucv, used to prove that one can interchange limits and ito or stratonovich integrals, provide the same result when one uses.
However, one can of course still make sense of differential equations provided one exhibits a rough path lift, existence of such a (non-unique) lift is a consequence of the lyons–victoir extension theorem.

Cross-country cycling is defined by the terrain on which it is performed. Xc courses and trails consist of a mix of rough forest paths and singletrack (also referred to as doubletrack depending on width), smooth fireroads, and even paved paths connecting other trails. Until recently cross-country trails were deemed easy or intermediate, due to the concept that this discipline of mountain biking relies more on physical prowess than technical ability.
At the core of rough path theory is the so-called signature transform which, while being simple to define, has rich mathematical properties bringing in aspects of analysis, geometry, and algebra. Hambly and lyons (annals of math, 2010) built upon earlier work of chen, showing how the signature represents the path uniquely up to generalized.
