> "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.
