Solutions to BSDEs Driven by Multidimensional Fractional Brownian Motions

الملخص EN

We study more general backward stochastic differential equations driven by multidimensional fractional Brownian motions.

Introducing the concept of the multidimensional fractional (or quasi-) conditional expectation, we study some of its properties.

Using the quasi-conditional expectation and multidimensional fractional Itô formula, we obtain the existence and uniqueness of the solutions to BSDEs driven by multidimensional fractional Brownian motions, where a fixed point principle is employed.

Finally, solutions to linear fractional backward stochastic differential equations are investigated.
