  - "We compute the deficiency spaces of operators of the form \U0001D43B\U0001D434⊗̂
    \U0001D43C+\U0001D43C⊗̂ \U0001D43B\U0001D435, for symmetric \U0001D43B\U0001D434
    and self-adjoint \U0001D43B\U0001D435. This enables us to construct self-adjoint
    extensions (if they exist) by means of von Neumann's theory. The structure of
    the deficiency spaces for this case was asserted already in Ibort et al. [Boundary
    dynamics driven entanglement, J. Phys. A: Math. Theor. 47(38) (2014) 385301],
    but only proven under the restriction of \U0001D43B\U0001D435 having discrete,
    non-degenerate spectrum.@eng"
