Spectral estimates for fourth-order differential operator with periodic coefficients
D. M. Polyakov Southern Mathematical Institute Vladikavkaz Scientific Center of RAS, 53 Vatutin str., Vladikavkaz, 362025 Russia
Abstract:
We consider a self-adjoint fourth-order operator on the unit interval with real 1-periodic coefficients and Neumann–Dirichlet type boundary conditions. We determine eigenvalue asymptotics at high energy.
Keywords:
spectrum, fourth-order differential operator, eigenvalue asymptotics, fundamental matrix.
