Findings from University of Marne la Vallee in Probability Research Reported

  2012 APR 17 - (VerticalNews.com) -- "In this paper, we are interested in the asymptotic size of the rows and columns of a random Young diagram under a natural deformation of the Plancherel measure coming from Hecke algebras. The first lines of such diagrams are typically of order n, so it does not fit in the context of the work of Biane (Int Math Res Notices 4:179-192, 2001) and Aeniady (Probab," investigators in Marne la Vallee, France report.

  "Theory Relat Fields 136:263-297, 2006). Using the theory of polynomial functions on Young diagrams of Kerov and Olshanski, we are able to compute explicitly the first- and second-order asymptotics of the length of the first rows," wrote V. Feray and colleagues, University of Marne la Vallee.

  The researchers concluded: "Our method also works for other measures, for example those coming from Schur-Weyl representations."

  Feray and colleagues published their study in Probability Theory and Related Fields (Asymptotics of q-plancherel measures. Probability Theory and Related Fields, 2012;152(3-4):589-624).
