Stochastic calculus Integral calculus Mathematical finance Calculus of variations. The calculus has been applied to stochastic partial differential equations.
The calculus has applications for example in malllavin filtering. This page was last edited on 12 Octoberat In particular, it allows the computation of derivatives of random variables.

Malliavin calculus – Wikipedia
His calculus enabled Malliavin to prove regularity bounds for the solution’s density. Please help to improve this article by introducing more precise citations.
Retrieved from ” https: 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 finance to compute the sensitivities of makliavin derivatives.
Malliavin calculus is also called the stochastic calculus of variations.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.

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