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

The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. In particular, it allows the computation of derivatives of random variables.

Malliavin calculus – Wikipedia

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. By using this site, you agree to the Terms of Use and Privacy Policy.

Application du calcul de Malliavin aux équations différentielles stochastiques sur le plan

The calculus has calucl 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.

A simplified version of this theorem is as follows:. Retrieved from ” https: Views Read Edit View history.

The calculus has been applied to stochastic partial differential equations. A similar idea can be applied in stochastic analysis for the differentiation along a Cameron-Martin-Girsanov direction. June Learn how and when to remove this template message.

From Wikipedia, the free encyclopedia. The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives.

The calculus has applications in, for example, stochastic filtering. The calculus has been applied to stochastic partial differential equations as well.
