Erratum: ''The problem of deficiency indices for discrete Schrödinger operators on locally finite graphs'' [J. Math. Phys. (52), 063512 (2011)]
Résumé
In this note we answer negatively to our conjecture concerning the deficiency indices. More precisely, given any non-negative integer~$n$, there is locally finite graph on which the adjacency matrix has deficiency indices $(n,n)$.
