Contractions, Matrix Paramatrizations, and Quantum Information
M. C. Tseng
In this note, we discuss dilation-theoretic matrix parametrizations of contractions and positive matrices. These parametrizations are then applied to some problems in quantum infor…

Dilation Theoretic Parametrizations of Positive Matrices with Applications to Quantum Information
M. C. Tseng, V. Ramakrishna
This paper, dedicated to the memory of late Professor Tiberiu Constantinescu, discusses two parametrizations of positive matrices. The first, called the Schur-Constantinescu parame…

Parametrizations of Positive Matrices With Applications
M. C. Tseng, Hong Zhou, V. Ramakrishna
This paper reviews some characterizations of positive matrices and discusses which lead to useful parametrizations. It is argued that one of them, which we dub the Schur-Constantin…
