Abstract

We consider a Schr\"{o}dinger operator with a matrix potential defined in L2m(Q) by the differential expression Lu=Δu+Vu and the Neumann boundary condition, where Q is a d-dimensional parallelepiped and V a matrix potential, d2, m2.
We obtain the high energy asymptotics of arbitrary order for
a rich set of eigenvalues.
