$G$-martingale representation in the $G$-L'evy setting

Probability 2014-04-09 v1

Abstract

In this paper we give the decomposition of a martingale under the sublinear expectation associated with a GG-L'evy process X with finite activity and without drift. We prove that such a martingale consists of an Ito integral w.r.t. continuous part of a GG-L'evy process, compensated Ito-L'evy integral w.r.t. jump measure associated with XX and a non-increasing continuous GG-martingale starting at 0.
