Title of Talk | Hankel Operators and Combinatorial Identities |
Abstract | We show that every bounded Hankel operator H on the Hilbert space of square-summable sequences can be factored as H = MM^*, where M maps a space of square-integrable functions to their corresponding moment sequences. By expanding these functions in a Fourier series of orthogonal polynomials, we obtain identities that connect the entries of the Hankel matrices with the orthogonal polynomials. |
