His calculus enabled Malliavin to prove regularity bounds for the solution’s density.

A simplified version of this theorem is as follows:. This page was last edited on 12 Octoberat The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces.

Malliavin calculus – Wikipedia

The dde has been applied to stochastic partial differential equations. 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. This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.


Malliavin calculus

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. In particular, it allows the computation of derivatives of random variables.

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.
