Ito formula with jump

WebDownloadable (with restrictions)! We present an Itô formula for the Lp-norm of jump processes having stochastic differentials in Lp-spaces. The main results extend well-known theorems of Krylov to the case of processes with jumps, which can be used to prove existence and uniqueness theorems in Lp-spaces for SPDEs driven by Lévy processes. Web1 mrt. 2015 · In this paper, we investigate the averaging principle for stochastic delay differential equations (SDDEs) and SDDEs with pure jumps. By the Itô formula, the Taylor formula, and the Burkholder-Davis-Gundy inequality, we show that the solution of the averaged SDDEs converges to that of the standard SDDEs in the sense of pth moment …

In mathematics, Itô's lemma or Itô's formula (also called the Itô-Doeblin formula, especially in French literature) is an identity used in Itô calculus to find the differential of a time-dependent function of a stochastic process. It serves as the stochastic calculus counterpart of the chain rule. It can be heuristically … Meer weergeven A formal proof of the lemma relies on taking the limit of a sequence of random variables.
