Centrosymmetric Stochastic Matrices

Lei Cao, Darian McLaren, Sarah Plosker

We consider the convex set $Γ_{m, n}$ of $m \times n$ stochastic matrices and the convex set $Γ_{m, n}^{π} \subset Γ_{m, n}$ of $m \times n$ centrosymmetric stochastic matrices (stochastic…

Partitions of Equiangular Tight Frames

James Rosado, Hieu D. Nguyen, Lei Cao

We present a new efficient algorithm to construct partitions of a special class of equiangular tight frames (ETFs) that satisfy the operator norm bound established by a theorem of…
