Next\, we discuss related results on manifolds with boundary. We relate Dirichlet and Neumann eigenv alues for conformally covariant boundary value problems. If time permits\, we shall discuss related results for boundary operators of arbitrary orde r\, as well as for weighted graphs. This is joint work with Y. Canzani\, R . Gover\, R. Ponge\, A. Hassannezhad\, M. Levitin\, M. Karpukhin\, G. Cox and Y.
