The Weyl matrix balls corresponding to the matricial truncated Hamburger moment problem (2109.11900v1)
Published 24 Sep 2021 in math.CA and math.CV
Abstract: The main goal of the paper is to parametrize the Weyl matrix balls associated with an arbitrary matricial truncated Hamburger moment problem. For the special case of a non-degenerate matricial truncated Hamburger moment problem the corresponding Weyl matrix balls were computed by I. V. Kovalishina in the framework of V. P. Potapov's method of "Fundamental matrix inequalities".
