Abstract

We characterize the domains of all self-adjoint extensions of the two-interval minimal operator which associated with two general even order linear ordinary differential expressions in terms of real-parameter solutions of the two differential equations. This is for endpoints which are regular or singular and for arbitrary deficiency index.
