An update on spaces of embeddings

The Cerf-Morlet comparison theorem states that the group of diffeomorphisms of the compact n-ball which is the identity on the boundary is an (n+1)-fold loop space, whose (n+1)-fold de-looping is the homotopy-quotient of the group of the PL-homeom   more››

A Compactification of the space of Maps from Curves

We will present a new compactification of the moduli space of maps from pointed nonsingular complex projective stable curves to a nonsingular complex projective variety with prescribed ramification indices at the points. It will be explained that   more››

Optimal Strong Stability Preserving Time Discretizations

Traditional stability concepts for ODE solvers typically deal with linear equations and/or bounds involving inner-product norms only. Modern problems of interest are typically nonlinear and in many casesthe relevant bounds for the problem inv   more››

Primitive roots and the Euclidean algorithm

An integer s is called a primitive root modulo a prime p if the multiplicative set generated by s surjects onto all non-zero residue classes modulo p. Artin's primitive root conjecture states that all integers s other than -1 or squares are primitive   more››

Eigenvalues of random matrices and not the Riemann Hypothesis

Random matrix theory has been a hot topic in number theory, particularly since the Rudnick and Sarnak landmark work on the spacing of consecutive zeros of L-functions. This highly accessible talk has a far more elementary flavour, focusing on eigenva   more››

Modelling the Endothelial Cell Response to Fluid Flow

Following the onset of shear stress due to fluid flow endothelial cells polarise and elongate in the direction of flow. How the mechanical signal is transformed into an organised and directed response is poorly understood. A multi-scale cellular P   more››

Analysis of immune cell chemotaxis and signal integration

In response to an injury, immune cells are recruited to fight off infecting microbes and clear cellular damage. A number of chemicals, called chemoattractants, are produced at or near sites of infection and inflammation and diffuse into the surrou   more››

Root numbers and Selmer groups of elliptic curves

The theory of root numbers predicts when elliptic curves over number fields have rational points of infinite order. In this talk, we shall discuss results which bring together the root numbers and non-commutative Iwasawa theory. It is joint work with   more››

Elliptic Nets

Elliptic divisibility sequences are integer recurrence sequences, each of which is associated to an elliptic curve over the rationals together with a rational point on that curve. I'll give the background on these and present a higher-dimensional ana   more››

Financial Hedging of Operational Flexibility

We extend the framework of real options to value the compound timing option owned by a manager of an industrial asset. The operator has control over the production modes, but faces operational constraints which introduce path-dependency. Moreover,   more››

Emerging Infectious Disease, Pandemic Preparedness and Mathematical Models: How to Prepare When We Don't Know the Enemy?

The underlying contact structure among individuals that determines the pattern of disease transmission and the progression in time of this pattern are two crucial elements in understanding and controlling communicable disease spread within a socia   more››
