Bernoulli Lecture - Models of random growth and the Hamilton-Jacobi equation.

Organisers :
  • Konstantin Khanin

The phenomenon of KPZ (Kardar-Parisi-Zhang) universality was a very active research area in the last 10 years. One can say that it describes universal statistical properties of long directed optimal paths (geodesics) in 2D disordered environment. Apart from many physical applications, it is remarkable for extremely strong universality properties in ...

Low-dimensional and Complex Dynamics

02 - 06 December 2019
Organisers :
  • Magnus Aspenberg
  • Michael Benedicks
  • Jacek Graczyk
  • Feliks Przytycki

This conference is aimed towards both complex and real dynamics. The idea is to connect different techniques from several fi elds of mostly low-dimensional dynamics. While complex analytic maps are quite rigid in comparision to other families of maps often studied, perturbing such maps in an non-rigid way has shown to be of extreme importance ...

Statistics for Indirectly Measured Functional Data

30 March - 03 April 2020
Organisers :
  • Merle Behr
  • Aurore Delaigle
  • Sofia Olhede

Functional data such as space curves, images, and surfaces are seldom sensed directly; curves are often noisily and discretely sampled, images are subject to blurring and deformation, and surfaces are often obtained via indirect linear measurements. Understanding the generation of the observations then requires modelling the act of acquisition, and ...

Functional Data over Multidimensional Domains

27 April - 01 May 2020
Organisers :
  • John Aston
  • Anthony Davison
  • Shahin Tavakoli

Spatio-temporal modelling central to many modern applications, but the dimensionality of the domain of such data poses both conceptual and computational statistical challenges. These are exacerbated in a nonparametric setting, where questions related to asymptotic framework and invariance assumptions arise. The areas of functional data analysis and random field analysis ...

Bernoulli Lecture - Strictly and non-strictly positive definite functions on spheres - revisited

29 April 2020
Organisers :
  • Tilmann Gneiting

In classical papers, Iso Schoenberg (1938, 1942) laid the ground for the study of isotropic positive definite functions on Euclidean spaces and spheres, respectively. Subsequently, positive definite functions on Euclidean spaces have been studied extensively in spatial statistics and related fields. In contrast, positive definite functions on spheres ...

Statistics for Topological and Discrete Data

25 - 29 May 2020
Organisers :
  • Kathryn Hess Bellwald
  • Sofia Olhede
  • Katharine Turner

Topological and discrete data such as trees and networks constitute strongly non-Euclidean structures, often beyond the reach of traditional statistical tools. Their analysis is often challenged by computational tractability, as natural constraints such as permutation invariance are computationally hard to implement. Still, such data can be often transposed into more ...

Bernoulli Lecture - Empirical Optimal Transport: Inference, Algorithms, Applications

28 May 2020
Organisers :
  • Axel Munk

Optimal transport has a long standing history in different branches of science, originating from physics and logistics. Since its emergence as a rigorous mathematical concept in the last century it has influenced and shaped various areas within mathematics but it also has been proven to a be a remarkably rich ...

Geometrical Statistics and Functional Data

22 - 26 June 2020
Organisers :
  • Ian Dryden
  • Simón Lunagómez
  • Victor Panaretos

Important classes of functional data, such as random measures and random operators, are intrinsically constrained and need to be represented as elements of suitable non-Euclidean spaces, such as Hilbert manifolds. The interplay between the infinite dimensionality of their variation and the non-linearity of their representation space poses novel challenges for ...

Self-similar and self-replicating groups

13 - 17 July 2020
Organisers :
  • Alejandra Garrido
  • Volodymyr Nekrashevych
  • Zoran Šunić

This workshop is concerned both with the structure theory of locally compact groups acting on discrete structures, and various notions of self-similarity as seen e.g. in Grigorchuk's and Sidki's groups. A crucial link between the two subjects stems from Baumgartner-Willis' tree representation theorem which associates a self-similar group acting on ...

Geometry, Mechanics, and Dynamics. Conference in Honor of the 70th Birthday of Tudor Ratiu

20 - 24 July 2020
Organisers :
  • François Gay-Balmaz
  • Juan-Pablo Ortega

This conference contains contributions that give an overview of the current research in geometric mechanics. This scientific subject is simultaneously close to mathematics, physics, and engineering and its general philosophy consists in taking advantage of fruitful interactions between geometry on the one hand and dynamics and mechanics on the other. ...

From local to global structure

24 - 28 August 2020
Organisers :
  • Pierre-Emmanuel Caprace
  • Michael Giudici
  • Colin Reid
  • Stephan Tornier

A powerful theme in the structure theory of locally compact groups is that ‘local’ properties of the group can have ‘global’ implications for the structure of the group. A classical example is given by Lie groups and their locally defined Lie algebras. In this workshop we explore local-to-global mechanisms for ...

07 - 11 June 2021
Organisers :
  • Viviane Baladi
  • Mark Demers
  • Sébastien Gouëzel
  • Carlangelo Liverani
  • Françoise Pène

There has recently been an explosion of results about transfer operators acting on anisotropic Banach spaces, starting with correlation decay and the analyticity properties of the Ruelle dynamical zeta function of uniformly hyperbolic maps and flows. These techniques have been extended to hyperbolic systems withsingularities, but the results there ...
