Davoud Cheraghi: Quasi-periodic dynamics in complex dimension one

1:00pm, CM101

Quasi-periodic dynamics in one complex variable reveals fascinating interplays between geometric complex analysis and Diophantine approximations. The question of whether a nonlinear perturbation of a linear rotation is conjugate to a linear rotation (linearisation) dates back to more than a century ago, with remarkable contributions made by C. L. Siegel, A. D. Brjuno, and J.-C. Yoccoz. The behaviour of non-linearisable maps is very complicated. Indeed, there is not a single example of a non-linearisable map whose local dynamical behaviour is completely understood. There has been recent significant advances on this problem using renormalisation methods. This is an introductory talk to present some of these results.

Danny King: B-Mixing: Sum-rules to CKM

5:00pm, OC218

In this talk I will give an introduction to B-meson mixing, focusing on the determination of non-perturbative input through HQET sum rules. I will demonstrate how the sum rule works and then highlight the advantages of using it over alternative methods, i.e Lattice QCD, in the context of the bag parameter. Finally, I will illustrate the importance of mixing constraints for the determination of the CKM matrix and in testing the Standard Model.
