Our main concern is the spectral properties of $L_\\alpha$, which turn out to be quite different for $\\alpha\\le 1$ and for $\\alpha>1$. In particular,\n $L_\\alpha$ has a unique self-adjoint realization for $\\alpha\\le 1$ and many such realizations for $\\alpha>1$. In the more difficult case $\\alpha>1$ an analysis of non-elliptic pseudodifferential operators in dimension one is involved.","authors_text":"G. Rozenblum, M.
