Such vectors are in bijection with integer lattice points of certain integral polytopes, which are Minkowski sums of simplices. We also describe vertices of these polytopes, and construct corresponding shifted Young tableaux.8 pages, 5 figures, corrected typos, added referencesCombinatorics05E10text
