Galois groups of random polynomials

3 PM, 25 Nov 2025

In this seminar, Fields Medalist Manjul Bhargava proves the van der Waerden conjecture on counting polynomials with small Galois groups.

In 1936, Bartel van der Waerden predicted that among all monic integer polynomials of degree nn with absolute values of coefficients at most HH, only about O(Hn1)O(H^{n-1}) fail to have the full symmetric Galois group. This had been proved only for degrees up to four, through work by van der Waerden and later Sam Chow and Rainer Dietmann. In this seminar, Prof. Manjul Bhargava presents a proof of the conjectured bound in all degrees, showing that polynomials of large degree with smaller-than-expected Galois groups form only a thin exceptional set.
