The Birkhoff von Neumann Theorem states that any $ntimes n$ doubly stochastic matrix is a convex sum of permutation matrices.



Is this true for $mathbbN times mathbbN$ matrices as well? (if yes, then can you give a reference?)

          I don't know the exact answer to your question but I found a reference that should be useful. In L. Mirsky's book Transversal Theory (Academic Press, 1971, ISBN 0-12-498550-5), on p.213,

          I read:




          Birkhoff's theorem has been extended to infinite d.s. matrices, with the notion of convex closure in a suitable topological vector space replacing that of convex hull. For references to work in this field, see Mirsky (1).




          The reference Mirsky (1) is to the following paper:




          L. Mirsky, Results and problems in the theory of doubly-stochastic matrices,
          Z. Wahrscheinlichkeitstheorie 1 (1962–3), 319–334.
