Girsanov’s theorem in vector lattices
(Springer, 2019)In this paper we formulate and proof Girsanov’s theorem in vector lattices. To reach this goal, we develop the theory of cross-variation processes, derive the cross-variation formula and the Kunita–Watanabe inequality. ... -
The Itô integral for Brownian motion in vector lattices. Part1
(Elsevier, 2015)In this paper the Itô integral for Brownian motion is constructed in a vector lattice and some of its properties are derived. The assumption is that there exists a conditional expectation operator on the vector lattice and ... -
Quadratic variation of martingales in Riesz spaces
(Elsevier, 2014)We derive quadratic variation inequalities for discrete-time martingales, sub- and supermartingales in the measure-free setting of Riesz spaces. Our main result is a Riesz space analogue of Austinʼs sample function theorem, ...
