Ito chain
Itô's lemma is the version of the chain rule or change of variables formula which applies to the Itô integral. It is one of the most powerful and frequently used theorems in stochastic calculus. For a continuous n-dimensional semimartingale X = (X ,...,X ) and twice continuously differentiable function f from R to R, it states that f(X) is a semimartingale and, In mathematics, Itô's lemma or Itô's formula (also called the Itô-Doeblin formula, especially in French literature) is an identity used in Itô calculus to find the differential of a time-dependent function of a stochastic process. It serves as the stochastic calculus counterpart of the chain rule. It can be … Meer weergeven A formal proof of the lemma relies on taking the limit of a sequence of random variables. This approach is not presented here since it involves a number of technical details. Instead, we give a sketch of how one … Meer weergeven An idea by Hans Föllmer was to extend Itô's formula to functions with finite quadratic variation.

WebIto’s lemma provides a way to construct new SDE’s from given ones. It is the stochastic calculus counterpart of the chain rule in calculus. It can be understood by considering a Taylor series expansion and understanding how it should be modifled in this stochastic setting.
