Abstract:
We consider a spectral problem for a two-term fourth-order differential operator with nonsmooth potential. The boundary conditions involve a spectral parameter. We obtain eigenvalue asymptotics at high energy and a regularized trace formula for this operator.
Keywords:
fourth-order differential operator, eigenvalue asymptotics, trace formula, spectral parameter in boundary conditions.
