"Direct sums of trace maps and self-adjoint extensions"

Abstract:
We provide a simple criterion so that a countable infinite direct sum of 
trace (evaluation) maps is a trace map. This  gives an alternative 
approach to results recently obtained by Malamud-Neidhardt and 
Kostenko-Malamud about self-adjoint extensions of direct sums of 
symmetric operators. An example providing all self-adjoint realizations 
of the Laplace-Beltrami operator on cylindrical Riemannian manifolds 
with singular/denenerate metrics is presented.
