  "abstract": "We use Newton divided differences for calculation of Greene sums -- the rational functions determined by linear extensions of partially ordered sets. Identities for Greene sums generate relations for Newton divided differences and Arnold differential forms. Also generalizations of the Newton interpolation series which are indexed by sequences of partially ordered sets are received.",
