Join science writer Simon Singh on a whistle-stop tour through two decades of his bestselling books. 'Fermat’s Last Theorem' looks at one of the biggest mathematical puzzles of the millennium; 'The Code Book' shares the secrets of cryptology; 'Big Bang' explores the history of cosmology; 'Trick or Treatment' asks some hard questions about alternative medicine; and 'The Simpsons and Their Mathematical Secrets' explains how TV writers, throughout the show’s 35-year history, have smuggled in mathematical jokes.

On the classification of quantum lens spaces
Sophie Zegers
(TU Delft)
Abstract
In the study of noncommutative geometry, various of classical spaces have been given a quantum analogue. A class of examples are the quantum lens spaces described by Hong and Szymański as graph C*-algebras. The graph C*-algebraic description has made it possible to obtain important information about their structure and to work on classification. Moreover, every quantum lens space comes with a natural circle action, leading to an equivariant isomorphisms problem.
In this talk, Sophie Zegers will give an introduction on how to classify quantum lens spaces and how to obtain a number theoretic invariant in low dimensions and will briefly present some results from joint work with Søren Eilers on the equivariant isomorphism problem of low dimensional quantum lens spaces.

An N=4 SYM Collider at Finite Rank and Finite Coupling
Robin Karlsson
(Oxford )
Abstract
Energy correlations characterise the energy flux through detectors at infinity produced in a collision event. In CFTs, these detectors are examples of light-ray operators and, in particular, the stress tensor operator integrated over future null infinity. In N=4 SU(N_c) SYM, we combine perturbation theory, holography, integrability, supersymmetric localisation, and modern conformal bootstrap techniques to obtain predictions for such a collider experiment at finite coupling, both at finite number of colours, and in the planar limit. In QCD, the coupling runs with the angle between detectors, and there is a transition from perturbative to non-perturbative QCD. In N=4 SYM, a similar transition occurs when the coupling is varied, which we explore quantitatively. I will describe the physics underlying this observable and some of the methods used, particularly in regimes with analytical control.
