We show how to compute in a covariant way the WKB-type expansion for the transition probability density of the Markovian processes generated by general multiplicative noise Langevin equations. The method uses phase space functional integrals and normal coordinates around the classical path. We compa

Difference methods for solving the convection-diffusion equation are discussed. The superiority of Allen's approximation over central or upwind differences for one-dimensional problems is confirmed, the superiority being greatest when the boundary layer is very thin. Higher order methods give improv
