Feller generators with measurable lower order terms

Abstract: We study perturbations of Feller generators by ‘lower order terms’ with measurable coefficients. We investigate which properties of the original semigroup—such as positivity, conservativeness and the Feller property—are passed on to the perturbed semigroup. We give several examples and discuss applications in the theory of martingale problems and stochastic differential equations with measurable coefficients.
