The unreasonable effectiveness of p-adic Hodge theory
ESB 4127
Tue 28 Feb 2017, 3:30pm-4:30pm

Abstract

As its name is meant to suggest, the subject of p-adic Hodge theory was historically concerned with the relationship between different cohomology theories attached to p-adic algebraic varieties. Within p-adic Hodge theory, the concept of a perfectoid space (discussed in my PIMS lectures) arose quite naturally and has led to improvements in the subject which were in some sense "expected".

However, it also had several "unexpected" applications rather far afield. We'll survey three of these: Deligne's weight-monodromy conjecture (Scholze); Galois representations associated to torsion cohomology of arithmetic groups (Scholze, Caraiani-Scholze); and the direct summand conjecture of commutative algebra (Andre, Bhatt).

Galois cyclic covers of the projective line and pencils of Fermat hypersurfaces
MATX 1102
Mon 6 Mar 2017, 3:00pm-4:00pm

Abstract

Classically, there are two objects that are particularly interesting to algebraic geometers: hyperelliptic curves and quadrics. The connection between these two seemingly unrelated objects was first revealed by M. Reid, which roughly says that there’s a correspondence between hyperelliptic curves and pencil of quadrics. I’ll give a brief review of Reid’s work and then describe a higher degree generalization of the correspondence.

Finite-order correlation length of the |\varphi|^4 spin model in four dimensions
Wed 8 Mar 2017, 3:00pm-4:00pm

Abstract

The correlation length of order p for the |\varphi|^4 spin model (a continuous-spin version of the O(n) model) is a normalization of the p-th moment of its two-point function. We will outline the proof (based on a renormalisation group method of Bauerschmidt, Brydges, and Slade) that, in the upper-critical dimension 4, this quantity undergoes mean-field scaling with a logarithmic correction as the critical point for this model is approached from above (for sufficiently weak coupling). Via a supersymmetric integral representation, this result also extends to the weakly self-avoiding walk with a contact attraction, for which the correlation length of order p is closely related to the mean p-th displacement of the walk. This is joint work with Roland Bauerschmidt, Gordon Slade, and Alexandre Tomberg.
