Harnack Type Inequalities for Matrices in Majorization

Research output: Contribution to journalArticlepeer-review

Abstract

Following the recent work of Jiang and Lin (2020) [12], we present more results (bounds) on Harnack type inequalities for matrices in terms of majorization (i.e., in partial products) of eigenvalues and singular values. We discuss and compare the bounds derived through different ways. Jiang and Lin's results imply Tung's version of Harnack's inequality (1964) [19]; our results are stronger and more general than Jiang and Lin's. We also show some majorization inequalities concerning Cayley transforms. Some open problems on spectral norm and eigenvalues are proposed.
