Description

Malliavin's probabilistic proof of Hormander's criterion can be considerably simplified using some rough path theory - at the end. In our case, we are interested in non-Markovian SDEs, where the non-Markovian aspect finds its source in the presence of delays. As such - I shall present a framework for RDEs with delays. Extensions if time allows. - I will show the application to finding a simple spanning condition of "Hormander-type" for delayed SDEs/RDEs which garantees smoothness of densities. Malliavin calculus is kept to the minimum. This is extracted from a joint body of work with I. Ekren.
