Discrete stochastic integration in Riesz spaces

Discrete stochastic integration in Riesz spaces In this work we continue the developments of Kuo et al.

The discrete stochastic integral is considered both in terms of a weighted sum of differences and via bilinear vector-valued forms.

Abstract

In this work we continue the developments of Kuo et al. (Indag Math 15:435–451, 2004; J Math Anal Appl 303:509–521, 2005) with the construction of the martingale transform or discrete stochastic integral in a Riesz space (measure-free) setting. The discrete stochastic integral is considered both in terms of a weighted sum of differences and via bilinear vector-valued forms. For this, analogues of the spaces L 2 and Mart2 on Riesz spaces with a conditional expectation operator and a weak order unit are constructed using the f-algebra structure of the universal completion of the Riesz space and properties of the extension of the conditional expectation to its natural domain.
