Abstract
We are dealing with possibly degenerate second-order parabolic operators whose coefficients are infinitely differentiable with respect to the space variables and only measurable with respect to the time variable. We impose the Hörmander condition on the diffusion coefficients and prove that the solutions of the corresponding equations with right-hand sides which are infinitely differentiable in the space variables in a space-time domain also have this property.
