In this article, we consider the problem of obtaining general Hermite type approximations for densities of uniformly elliptic multi-dimensional diffusions with smooth coefficients in small time. These approximations resemble the Itô chaos expansions for square integrable random variables on Wiener space. The proofs are constructive and the approximations are explicit enough so that they can be used for constructing algorithms of approximation in the total variation sense. As examples, we provide some density expansions on some multi-dimensional examples.
