Application du calcul de Malliavin aux équations différentielles stochastiques sur le plan
From Wikipedia, the free encyclopedia. Please help to improve this article by introducing more precise citations. The calculus has applications in, for example, stochastic filtering. Malliavin calculus mlliavin also called the stochastic calculus of variations. 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.
Malliavin calculus – Wikipedia
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. This page was last edited on 12 Octoberat The calculus has applications for example in stochastic filtering.
Retrieved from ” https: Views Read Edit View jalliavin.
The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities of financial derivatives. His calculus enabled Malliavin to prove regularity bounds for the solution’s density.
The calculus has been applied to stochastic partial differential equations as well. Stochastic calculus Integral calculus Mathematical finance ,alliavin of variations.
The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces.
A simplified version of this theorem is as follows:. All articles with unsourced statements Articles with unsourced statements from August Articles lacking in-text citations from June All articles lacking calcu, citations.
