We study the facial structure of the polytope Ωtnin Rn×nconsisting of the tridiagonal doubly stochastic matrices of order n. We also discuss some subclasses of Ωtnwith focus on spectral properties and rank formulas. Finally we discuss a connection to majorization. © 2004 Elsevier Inc. All rights reserved.
