The regularity in the initial conditions of every Markov transition kernel associated to the equation is studied by a simple direct approach. A by-product of the technique is the equivalence of all transition probabilities associated to every Markov transition kernel.17 pagesProbabilityMathematical PhysicsAnalysis of PDEs76D05; 60H15; 35Q30; 60H30; 76M35text
