Non-degeneracy of Wiener functionals arising from rough differential equations. (English) Zbl 1175.60034
The authors consider the stochastic differential equation of type: $dY=V(Y)dX+V_0(Y)dt,\tag{1}$ where $$X$$ is a non-degenerate multidimensional Gaussian proces. The signal $$X$$ is such, that the equation (1) makes sense as rough differential equation. The authors prove the existence of a density for solutions to equation (1). In demonstration of this result they combine some facts of theory of Malliavin calculus and rough paths analysis.
