Dissipative operators, symplectic geometry, and limit-circle solutions

For a general symmetric ordinary differential expression M and a positive weight function w, the authors characterized the dissipative and strictly dissipative extensions of the minimal operator generated by M in terms of subspaces of a symplectic geometry space. Here we characterize these subspaces in terms of LC solutions, namely, we characterize the boundary conditions of the dissipative and strictly dissipative extensions by LC solutions in a Hilbert space.
