New mathematical physics data have been reported by scientists at University of Insubria

  2008 NOV 24 - (VerticalNews.com) -- According to a study from Como, Italy, "A main issue in superstring theory are the superstring measures. D'Hoker and Phong showed that for genus two these reduce to measures on the moduli space of curves which are the product of modular forms of weight eight and the bosonic measure."

  "They also suggested a generalisation to higher genus. We showed that their approach works, with a minor modification, in genus three and we announced a positive result also in genus four," wrote S.L. Cacciatori and colleagues, University of Insubria.

  The researchers concluded: "Here we give the modular form in genus four explicitly. Recently, S. Grushevsky published this result as part of a more general approach."

  Cacciatori and colleagues published the results of their research in Letters in Mathematical Physics (Genus four superstring measures. Letters in Mathematical Physics, 2008;85(2-3):185-193).
