Completeness of boundary traces of eigenfunctions
Completeness of boundary traces of eigenfunctions
In this paper, we study the boundary traces of eigenfunctions on the boundary of a smooth and bounded domain. An identity derived by BƤcker, FĆ¼rstburger, Schubert, and Steiner [āBehaviour of boundary functions for quantum billiardsā, J. Phys. A 35 (2002) 10293ā10310], expressing (in some sense) the asymptotic completeness of the ā¦
