Seminars for the week of February 28, 2005
Colloquium
Thursday, 3:30, in VinH 16Professor Adrian Diaconu
of Columbia University
will speak on
"Twisted Fermat Curves Over Totally Real Fields"
Let p be an odd prime number, and consider the twisted affine Fermat curve $x^p+y^p =\Delta$ with a rational $\delta$. A well-known theorem of Faltings implies that, for $p\geq 5$, the twisted affine Fermat curve has finitely many rational points, thanks to Wiles' proof of the Fermat Last Theorem. In this talk, we will introduce a different idea to study twisted affine Fermat curves. It is based on the connection between the central value of the Hasse-Weil L-function associated to the twisted affine Fermat curve, and the rank of its Jacobian, as predicted by the Birch and Swinnerton-Dyer conjecture. We will give a sufficient (effective) condition for the twisted affine Fermat curves to have no rational points in terms of the non-vanishing at the central point of certain L-functions. Then, using analytic methods, we will conclude that our sufficient condition is satisfied infinitely often, for any prime p. (This is joint work with Y. Tian).
