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. His calculus enabled Malliavin to prove regularity mallliavin for the solution’s density. This article includes a list of referencesrelated reading or external linksbut its sources remain unclear because it lacks inline citations.
From Wikipedia, the free encyclopedia.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces. A similar idea can be applied in stochastic analysis for the differentiation along a Cameron-Martin-Girsanov direction. The calculus has applications for example in stochastic filtering.
The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives. Retrieved from ” https: A simplified version of this theorem is as follows:.
In particular, it allows the computation of derivatives of random variables. Stochastic calculus Integral calculus Mathematical finance Calculus of variations.
The calculus has been applied to stochastic partial differential equations as well. Please help to improve this article by introducing more precise citations.
