On the spectrum of a vector Schrödinger operator

  • R. S. Ismagilov
  • A. G. Kostyuchenko


We consider the asymptotics of the spectrum of a Sturm-Liouville operator acting on a space of vector functions and show that this asymptotics is affected by “rotation” of eigenvectors of the potential. A similar result is obtained for a vector Schrödinger operator.
