Left definite theory of regular self-adjoint operators in a Sobolev space was developed a rew years ago when the boundary conditions were separated, the separation being necessary in order to properly define the Sobolev inner product. We show how this may be extended when the boundary conditions are

We study a family of differential operators L in two variables, depending on the coupling parameter 0 that appears only in the boundary conditions. Our main concern is the spectral properties of L , which turn out to be quite different for < 1 and for > 1. In particular, L has a unique self-adjoint
