Views Read Edit View history. 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.
His calculus enabled Malliavin to prove regularity bounds for the solution’s density. In particular, it allows the computation of derivatives of random variables. Malliavin calculus is also called the stochastic calculus of variations.
The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives. Please help to improve this article by introducing more precise citations. From Wikipedia, the free encyclopedia.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces.

In probability theory and related fields, Malliavin calculus is a set of mathematical techniques and ideas that extend the mathematical field of calculus of calucl from deterministic functions to stochastic malliavinn.

The calculus mmalliavin 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 has applications in, for example, stochastic filtering.
