One Day Ergodic Theory Meeting is a "wandering" seminar series supported by an LMS grant and organised by 10 UK universities: Birmingham, Bristol, Durham, Exeter, Loughborough, Manchester, The Open University, Queen Mary, St. Andrews and Warwick. 

The January 2023 Ergodic Theory Meeting will be hosted by Queen Mary's School of Mathematical Sciences. 

Please see below for the schedule:

14:00 - 15:00 Ben Krause, 
Title: Pointwise Ergodic Theory, Pre-COVID
Abstract: In this talk I will survey the state of pointwise ergodic theory up to 2020, emphasizing the role of Bourgain

15:00 - 15:30 Refreshments 

15:30 - 16:30 Demi Allen
Title: Shrinking targets and recurrence
Abstract: In this talk, time permitting(!), I aim to discuss two somewhat disjoint yet related topics. First of all, I aim to discuss Hausdorff measure results for shrinking target sets in self-conformal sets. Secondly, I plan to discuss almost sure recurrence rates of Gibbs measures for Holder continuous potentials over subshifts of finite type. The first part of the talk will be based on joint work with Bal´azs B´ar´any (Budapest), and the latter part will be based on joint work with Simon Baker (Loughborough) and Bal´azs B´ar´any (Budapest). 

16:45 - 17:45 Radhakrishnan Nair
Title: On Good Universality and the Riemann Hypothesis
Abstract: We use subsequence ergodic theorems applied to Boole’s transformation and its variants and their invariant measures on the real line to give new characterisations of the Lindelhof Hypothesis and the Riemann hypothesis. This builds on earlier work of R. L. Adler and B. Weiss, M. Lifshits and M. Weber, J. Steuding, J. Lee and A. I. Surijaya using Birkhoff’s ergodic theorem and probability theory.  The talk is on work with Jean-Louis Verger-Gaugry and Michel Weber. 

18:15  Early Dinner

Some support is available for participants and any queries regarding support should be sent to Reem Yassawi from Queen Mary University of London, r.yassawi@qmul.ac.uk or Thomas Jordan from the University of Bristol, thomas.jordan@bristol.ac.uk
