| Monodromy computations in topology and number theory |
|
The monodromy of a family of varieties is a measure of how homology classes vary. Surprisingly, many familiar ideas in number theory, such as Galois representations and Cohen-Lenstra heuristics, are closely linked to monodromy of specific families. In this talk I will define monodromy, explain some number theoretic applications, and describe original work of computing monodromy for moduli spaces of covers of the projective line (Hurwitz spaces). This work generalizes previous results of Achter-Pries, Yu and Hall on hyperelliptic families. Only basic knowledge of algebraic topology and number theory is required. |

ABSTRACT |
In his 1987 Inventiones paper, Dr. Noam Elkies proved that every elliptic curve over [math]\displaystyle{ \mathbb{Q} }[/math] has infinitely many supersingular primes. We shall discuss some of the mathematics needed to prove this result and give a proof.}
