## Bernoulli Lecture - Continuous-time random matching

We show the existence of independent random matching of a large population in a continuous-time dynamical system, where the matching intensities could be general non-negative jointly continuous functions on the space of type distributions and the time line. In particular, we construct a continuum of independent continuous-time Markov processes that is derived from random mutation, ...

## Cellular covers of local groups

This is joint work with Ramon Flores. Emmanuel Dror Farjoun asked whether the composition of a localization and a cellularization functor is always idempotent. Ramon Flores gave a negative answer for such functors in the category of spaces. We provide now a group theoretical counter-example based on the intriguing computation by Ol’shanskii of the Schur ...

## Reconnection, vortex knots and the fourth dimension

Vortex knots tend to unravel into collections of unlinked circles by writhe-preserving reconnections. We can model this unravelling by examining the world line of the knot, viewing each reconnection as a saddle point transition. The world line is then seen as an oriented cobordism of the knot to a disjoint collection of circles. Cap each ...

## Quantitative distribution of Hecke eigenvalues for simple groups

Abstract: Families of automorphic forms have seen a lot of interest over recent years. An approach to study them is through their Hecke eigenvalues. In this talk I want to explain current and recent work on the distribution of those eigenvalues in families of spherical automorphic forms. (Joint work with T. Finis and N. Templier.)

## Knotoids and virtual knot theory

Knotoids are open-ended knot diagrams whose endpoints can be in different regions of the diagram. Two knotoids are said to be isotopic if there is a sequence of Reidemeister moves that connects one diagram to the other without moving arcs across endpoints. The definition is due to Turaev. We will discuss three dimensional interpretations of ...

## Bernoulli Lecture - Systemic Risk with Endogenous Cycles

Biography Robert Engle, the Michael Armellino Professor of Management and Financial Services at New York University Stern School of Business, was awarded the 2003 Nobel Prize in Economics for his research on the concept of autoregressive conditional heteroskedasticity (ARCH). Professor Engle is an expert in time series analysis with a long-standing interest in the analysis ...

## NTD 2017 - Many cubic surfaces contain rational points

I will discuss the arithmetic of cubic surfaces and show how the arithmetic of Mordell curves allows one to say something unconditional about the existence of rational points on a family of cubic surfaces.

## NTD 2017 - Hodge theory and atypical intersections

Given a smooth family of quasiprojective complex varieties $f:X \rightarrow S$, one would like to understand the locus of points $s \in S$ whose fiber $X_s$ admits more Hodge classes than the very general fiber. In this talk I will describe a general conjecture (and some results) concerning this locus in terms of exceptional intersections. ...

## NTD 2017 - Multiplicative functions and rational points in families of varieties

(Joint work with Daniel Loughran.) Given a family of varieties over Q, we consider the problem of counting the number of varieties in this family which have a rational point. For suitable families over P^1, we will show how to obtain correct order lower bounds for this counting problem and thereby answer a question of ...

## NTD 2017 - Rational Points on Picard modular surfaces, and non-vanishing of L-values

This talk will describe ongoing joint work, and some progress, with M. Dimitrov on the expected paucity of rational points on Picard modular surfaces of large level. There is an analytic component which involves non-vanishing of L-values and a geometric component involving intersections.
