The square of the Fermat quotient.
We solve a problem of Bombieri, stated in connection with the «prime number theorem» for function fields.
In this report, prepared specially for the program of the , we describe how, in joint work with K. Soundararajan and Antal Balog, we have developed the notion of “pretentiousness” to help us better understand several key questions in analytic number theory.
For an odd prime, we show that the Fekete polynomial has zeros on the unit circle, where . Here is the probability that the function has a zero in , where each is with y . In fact has absolute value at each primitive th root of unity, and we show that if for some then there is a zero of close to this arc.
We report on a large-scale project to investigate the ranks of elliptic curves in a quadratic twist family, focussing on the congruent number curve. Our methods to exclude candidate curves include 2-Selmer, 4-Selmer, and 8-Selmer tests, the use of the Guinand-Weil explicit formula, and even 3-descent in a couple of cases. We find that rank 6 quadratic twists are reasonably common (though still quite difficult to find), while rank 7 twists seem much more rare. We also describe our inability to find...
