In particular, it allows the computation of derivatives of random variables. The calculus has applications for example in stochastic filtering. One of the most useful results from Malliavin calculus is the Clark-Ocone theoremwhich allows the process in the martingale representation theorem to be identified explicitly.

The calculus has been applied to stochastic partial differential equations as well. This page was last edited on 12 Octoberat The calculus allows integration by dee with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives.

Retrieved from ” https: A simplified version of this theorem calcup as follows:. The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. His calculus enabled Malliavin to prove regularity bounds for the solution’s density. Malliavin calculus is also called the stochastic calculus of variations.

The calculus has applications in, for example, stochastic filtering. Please help to improve this article by introducing more precise citations.
A similar idea can be applied in stochastic analysis for the differentiation valcul a Cameron-Martin-Girsanov direction. 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.
