Stochastic calculus Integral calculus Mathematical finance Calculus of variations. The calculus has been applied to stochastic partial differential equations as well.
This page was last edited on 12 Octoberat One of the most useful results from Malliavin calculus is mmalliavin Clark-Ocone theoremwhich allows the process in the martingale representation theorem to be identified explicitly. Malliavin calculus is also called the stochastic calculus of variations.

In probability theory and related fields, Malliavin calculus is a set of mathematical techniques and ideas that extend the mathematical field of calculus of variations from deterministic functions to stochastic processes.
A simplified version of this theorem is as follows:. The calculus has been applied to stochastic partial differential equations.
Retrieved from ” https: From Wikipedia, the free encyclopedia. The calculus has applications for example in stochastic filtering.
A similar idea can be applied in stochastic analysis for the differentiation along a Cameron-Martin-Girsanov direction. The calculus allows integration by parts with random variables ; this operation is used in mathematical malilavin to compute the sensitivities of financial derivatives.
This article includes a list of claculrelated reading or external linksbut its sources remain unclear because it lacks inline citations. Please help to improve this article by introducing more precise citations. In particular, it allows the computation of derivatives of random variables.
