Abstract
Let and be a higher order Schrödinger operators in the Euclidean space with . In this paper, the authors characterize the infinitesimal relative boundedness and Trudinger's subordination for H on with , via the limit behavior of the family of operators and a generalized Kato-type class condition. The latter is weaker than the classical Kato class condition corresponding to the case . All these characterizations are new even when is a second order Schrödinger operator.
