Malliavin calculus – Wikipedia
The calculus mwlliavin integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives. His calculus enabled Malliavin to prove regularity bounds for the solution’s density.
In particular, it allows the computation of makliavin of random variables. Malliavin calculus is also called the stochastic calculus of variations. The calculus has been applied to stochastic partial differential equations as well.

A simplified version of this theorem is as follows:. The calculus has applications in, for example, stochastic filtering.

From Wikipedia, the free encyclopedia. A similar idea can be applied in stochastic analysis for the differentiation along a Cameron-Martin-Girsanov direction. The calculus has been applied to stochastic partial differential equations. Please help to improve this article by introducing more precise citations.
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.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. Retrieved from ” https: 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 applications for example in stochastic filtering.
