On the combinatorics of iterated stochastic integrals
نویسنده
چکیده
Abstract. This paper derives several identities for the iterated integrals of a general semimartingale. They involve powers, brackets, exponential and the stochastic exponential. Their form and derivations are combinatorial. The formulae simplify for continuous or finite-variation semimartingales, especially for counting processes. The results are motivated by chaotic representation of martingales, and a simple such application is given.

Greedy decomposition integrals
In this contribution we define a new class of non-linear integrals based on decomposition integrals. These integrals are motivated by greediness of many real-life situations. Another view on this new class of integrals is that it is a generalization of both the Shilkret and PAN integrals. Moreover, it can be seen as an iterated Shilkret integral. Also, an example in time-series analysis is prov...
متن کاملThe using of Haar wavelets for the expansion of fractional stochastic integrals
Abstract: In this paper, an efficient method based on Haar wavelets is proposed for solving fractional stochastic integrals with Hurst parameter. Properties of Haar wavelets are described. Also, the error analysis of the proposed method is investigated. Some numerical examples are provided to illustrate the computational efficiency and accuracy of the method.

Let X = (Xt,Ft)t≥0 be a continuous local martingale with quadratic variation process 〈X〉 and X0 = 0. Define iterated stochastic integrals In(X) = (In(t, X),Ft) (n ≥ 0), inductively by
متن کاملCombinatorics of Poisson stochastic integrals with random integrands
We present a self-contained account of recent results on moment identities for Poisson stochastic integrals with random integrands, based on the use of functional transforms on the Poisson space. This presentation relies on elementary combinatorics based on the Faà di Bruno formula, partitions and polynomials, which are used together with multiple stochastic integrals, finite difference operato...
متن کاملThe Geometry of Iterated Stratonovich Integrals
We give a summary on the geometry of iterated Stratonovich integrals. For this exposition, we always have the connection to stochastic Taylor expansion in mind. In particular, we believe that “cubature on Wiener space” is best understood in the setting presented in this text. Besides cubature on Wiener space, we also give a second application regarding the heat kernel on nilpotent free Lie groups.
