Abstract
We investigate a fourth-order boundary value problem with discontinuous coe¢ cients, functional many points and transmission conditions.In this problem, boundary conditions contain not only endpoints of the considered interval, but also a point of discontinuity, a ...nite number internalpoints and abstract linear functionals. We discuss asymptotic distribution ofits eigenvalues. Finally, we obtain asymptotic formulas for the eigenvalues ofthe problem in sectors of the complex plane.
