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. In particular, it allows the computation of mallizvin of random variables. Malliavin calculus is also called the stochastic calculus of variations.
The calculus has been applied to stochastic partial differential equations as well.
The calculus allows integration by parts with random variables ; this operation is used in mathematical finance to compute the sensitivities malliagin financial derivatives. The calculus has applications in, for example, stochastic filtering. His calculus enabled Malliavin to prove regularity bounds for the solution’s density.
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. 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:. The existence of this adjoint follows from the Riesz representation theorem for linear operators on Hilbert spaces.
