New findings from University of Wisconsin in the area of mathematics published

  2008 NOV 24 - (VerticalNews.com) -- "We generalize the First Reconstruction Theorem of Kontsevich and Martin in two respects," scientists in the United States report.

  "First, we allow the target space to be a Deligne-Mumford stack. Second, under some convergence assumptions, we show it Suffices to check the hypothesis of H-2-generation not on the cohomology ring, but on an any quantum ring in the family given by small quantum cohomology," wrote M.A. Rose and colleagues, University of Wisconsin.

  The researchers concluded: "As an example the latter result is used to compute genus zero Gromov-Witten invariants of P(l, b)."

  Rose and colleagues published their study in American Journal of Mathematics (A Reconstruction theorem for genus zero Gromov-Witten invariants of stacks. American Journal of Mathematics, 2008;130(5):1427-1443).
