Introduction,For a better understanding of the content of the monograph, we will first outline the main content of the second chapter: direct and inverse spectral problems for classical Jacobi matrices and orthogonal polynomials on the real axis.可以任性 发表于 2025-3-25 01:42:13
Some Aspects of the Spectral Theory of Unbounded Operators,We hope that the reader is well acquainted with basic courses of mathematical and functional analysis, in particular with the theory of linear bounded operators in Hilbert spaces. Therefore, in this chapter we will recall only the basic concepts regarding unbounded self-adjoint operators, without which the book reading would be difficult.
