As of May 1 -May 3, 2002

 

Department Colloquium

Topic:        Counting field extensions of the rational numbers

Presenter:   Manjul Bhargava, Institute for Advanced Study

Date:          Wednesday, May 1, 2002, Time: 4:30 p.m., Location: Fine Hall 314

Abstract:    "Number fields" - i.e., finite extensions of the rational numbers - are perhaps the most fundamental objects in algebraic number theory. Yet, amazingly, we have almost no idea how to systematically enumerate them, or even describe their distrbution asympotically with respect to basic invariants. The only general guess on their distribution is an old and simple (but very elusive!) conjecture of Linnik.  In this talk, we will state Linnik's conjecture, and present some old and new results that allow for a proof in the case of number fields of degree up to four.

Princeton University/IAS Number Theory Seminar 

Topic:        L and epsilon factors for some representations of GSp(4)

Presenter:   Brooks Roberts,  University of Idaho

Date:          Thursday, May 2, 2002, Time: 4:30, Location: Fine Hall 322

Abstract:    In a previous work we proved an analogue for GSp(4) of the dihedral case of the Langlands-Tunnell Theorem. This involved defining some L-packets for GSp(4). In this talk we will discuss the L and epsilon factors associated to the generic elements of these local nonarchimedean L-packets by the Novodvorsky integral representation. We will also discuss the problem of finding canonical vectors in such generic representations which represent their L-factors.
