Decay bounds on eigenfunctions and the singular spectrum of unbounded Jacobi matrices
Jan Janas, Serguei Naboko, Günter Stolz
Bounds on the exponential decay of generalized eigenfunctions of bounded and unbounded selfadjoint Jacobi matrices are established. Two cases are considered separately: (i) the cas…
The critical temperature for the BCS equation at weak coupling
Rupert L. Frank, Christian Hainzl, Serguei Naboko +1
For the BCS equation with local two-body interaction , we give a rigorous analysis of the asymptotic behavior of the critical temperature as . We derive necessary an…
Boundary triplets and M-functions for non-selfadjoint operators, with applications to elliptic PDEs and block operator matrices
Malcolm Brown, Marco Marletta, Serguei Naboko +1
Starting with an adjoint pair of operators, under suitable abstract versions of standard PDE hypotheses, we consider the Weyl M-function of extensions of the operators. The extensi…
