We consider the essential self-adjointness for formally self-adjoint Schrödinger-like operators with real principal type, but not necessarily elliptic, symbols. In order to show the essential self-adjointness, we need geometric conditions even for operators on the Euclidean space with asymptotically constant coefficients. We explain how the essential self-adjointness can be proved under the null non-trapping condition.
