L. V. Kritskov Lomonosov Moscow State University, Moscow, Russian Federation
Abstract:
Result on the uniform, over the entire real line, equiconvergence of spectral expansions related to the self-adjoint extension of a general differential operation of any even order with coefficients from the one-dimensional Kato class, with the Fourier integral expansion is presented. The statement is based on the obtained uniform estimates for the spectral function of this operator.
Keywords:
self-adjoint even-order differential operator, spectral expansion, equiconvergence.
