Infinite Doubly Stochastic Matrices [PDF]

open access: yesCanadian Mathematical Bulletin, 1962
This note proves two propositions on infinite doubly stochastic matrices, both of which already appear in the literature: one with an unnecessarily sophisticated proof (Kendall [2]) and the other with the incorrect assertion that the proof is trivial (Isbell [l]).

Diagonals of Doubly Stochastic Matrices [PDF]

open access: yesCanadian Mathematical Bulletin, 1972
Let A be an additive abelian group and Dn(A) the set of those n x n matrices over A all of whose row and column sums are equal. Such matrices can be regarded as a possible generalization of doubly stochastic real matrices; alternatively, if A is a commutative ring, it turns out that Dn(A) is exactly the image of the permutation representation of Sn ...

Directed graphs, Hamiltonicity and doubly stochastic matrices [PDF]

open access: yesRandom Structures & Algorithms, 2004
AbstractWe consider the Hamiltonian cycle problem embedded in singularly perturbed (controlled) Markov chains. We also consider a functional on the space of stationary policies of the process that consists of the (1,1)‐entry of the fundamental matrices of the Markov chains induced by the same policies.

Majorization-constrained doubly stochastic matrices [PDF]

open access: yesLinear Algebra and Its Applications, 2003
We study subpolytopes Ωn(d) of the Birkhoff polytope Ωn of doubly stochastic matrices of order n whose rows and columns (or just one row or just the main diagonal) are majorized by a given stochastic vector d.

Matrices Doubly Stochastic by Blocks

Canadian Journal of Mathematics, 1977
The present work stems from the following classical result, due to G. H. Hardy, J. E. Littlewood, G. Pólya [7], and R. Rado [10].THEOREM 1. Concerning a pair of n-tuples x, y ϵ Rn, the following four statementsare equivalent:(a) for every continuous, convex function f : R ...
