Geometric Properties and Distance Inequalities on Grassmannians

Tin-Yau Tam, Xiang Xiang Wang

In this paper we obtain inequalities for the geometric mean of elements in the Grassmannians. These inequalities reflect the elliptic geometry of the Grassmannians as Riemannian ma…

Weak log majorization and determinantal inequalities

Tin-Yau Tam, Pingping Zhang

Denote by $¶_{n}$ the set of $n \times n$ positive definite matrices. Let $D = D_{1} \oplus \dots \oplus D_{k}$ , where $D_{1} \in ¶_{n_{1}}, \dots, D_{k} \in ¶_{n_{k}}$ with $n_{1} + \dots + n_{k} = n$ . P…
