Spectral analysis of a fourth-order nonselfadjoint operator with nonsmooth coefficients
D. M. Polyakov Research Institute for Mathematics, Voronezh State University, Voronezh, Russia
Abstract:
Using the method of similar operators, we study the spectral properties of a fourth-order differential operator with two types of classical boundary conditions. We obtain asymptotics for the spectrum and estimates for the spectral decompositions of this operator. We construct the semigroup generated by the opposite fourth-order differential operator.
Keywords:
fourth-order differential operator, spectrum of operator, method of similar operators.
