Weyl sums for quadratic roots

We study exponential sums of Weyl type taken over roots of quadratic congruences. We are particularly interested in the situation where the range of summation is small compared to the discriminant of the polynomial. We are then able to give a number of arithmetic applications.

This is work which is joint with W. Duke and H. Iwaniec.

On the section conjecture in anabelian geometry
The section conjecture of Grothendieck's anabelian geometry speculates about a description of the set of rational points of a hyperbolic curve over a number field entirely in terms of profinite groups and Galois theory. In the talk we will discuss local to global aspects of the conjecture, and what can be achieved when sections with additional group theoretic properties are considered.
