Abstract

In this paper, we study the truncated matrix moment problem in one variable through recursive matrix extensions. \ We give necessary and sufficient conditions for a recursive matrix extension of finite data to be a matrix moment sequence in the classical cases of Hamburger, Stieltjes, and Hausdorff moment problems. \ We also discuss matricial subnormal completion and matricial kk--hyponormal completion problems and provide an analog of Stampfli's Theorem on flat propagation for 22--hyponormal matricial weighted shifts.
