Given a control system on a compact manifold M, we study conditions for the foliation defined by the accessible sets to be dense in M. For this, we relate the control system to a stochastic differential equation and, by ...

This paper proposes an empirical asset pricing test based on the homogeneity of the factor risk premia across risky assets. Factor loadings are considered to be dynamic and estimated from data at higher frequencies. The ...

By the effect of aggregating currents, some systems display an effective diffusion coefficient that becomesnegative in a range of the order parameter, giving rise to bistability among homogeneous states (HSs). By applyinga ...

Change detection is a topic of great interest in remote sensing. A good similarity metric to compute the variations among the images is the key to high-quality change detection. However, most existing approaches rely on ...

We study two actions of a stochastic flow psi(t) on the space of 0-currents T of a differentiable manifold M. In particular, we give conditions on a current T to be invariant under these actions. Also, we apply our results ...

We consider homogeneous STIT tessellations Y in the-dimensional Euclidean space R-l and show that the (spatial) beta-mixing rate converges to zero
