20-24 Nov 2017 Villeurbanne (France)
This week-long event, scheduled between November 20 and November 24, 2017 at the University of Lyon 1, is a combined school and workshop focusing primarily on the rich interactions between ultrafilters, topological dynamics and ergodic theory and applications to Ramsey theory. This event is part of the thematic semester “Graphs, Groups and Dynamics”.

The aim of this programme is to bring together mathematicians and logicians working on/interested in various topics on the border of model theory, topology and set theory. The leading themes are topological dynamics and descriptive set theoretic methods in model theory. Apart from the state of the art lectures by leading experts, two tutorials, each consisting of 3 one-hour talks on the main themes of the meeting, are being planned. The meeting will give opportunity for discussion and collaboration between experts from different but related parts of logic. This may result in the future in discovering new interactions between model theory, topology and set theory.
There is no conference fee. However, all invited speakers and participants must register. Accommodation and food for all participants will be provided by the guest house of Tezpur University. Check in date at the guest house is 6th september, 2017 and check out is 13th september, 2017.

Title: Real-valued measurability and Lebesgue measurable sets
Abstract: I will show that the existence of atomlessly measurable cardinals does not settle the range of Lebesgue measure on the projective sets.
A 2-week summer school will take place at UC Irvine from Aug. 14 – 25, 2017. The topic of the school will be classification problems in ergodic theory. Lectures will be given by Peter Burton
, Matt Foreman
, and Brandon Seward
- The first week will treat positive classification results and associated tools. We will primarily focus on entropy theory, starting with the classical entropy theory for actions of countable amenable groups and ending with the quite recent developments of entropy theory for actions of countable non-amenable groups (in particular sofic groups).
- The second week will be concerned with anti-classification results: results showing that classifications are not possible with countable resources. We begin with a review of naive descriptive set theory and then discuss classification in this framework. We proceed to show that the classification problem is not solvable for Z-actions, even of real analytic diffeomorphisms of the torus. Finally, we place the classification problems in the hierarchy of analytic equivalence relations under Borel reducibility.
The deadline for applications is May 15, however late applications will still be considered on a case-by-case basis. Funding is available for US citizens and permanent residents (per grant restrictions). More information can be found here:
SGSLPS 2017 Spring meeting on “Borel Reducibility of Equivalence Relations”
Université de Lausanne (Unil), Amphipôle, Room 340
29 May 2017, 10:30 – 17:00
The SGSLPS 2017 Spring meeting on “Borel Reducibility of Equivalence Relations” will feature four hour-long talks by leading experts in the field. The first talk will be introductory and will aim at a general audience.
- Andrew Brooke-Taylor (University of Leeds, Leeds)
- Raphaël Carroy (Kurt Gödel Research Centre, Vienna)
- Julien Melleray (Université Claude Bernard Lyon 1, Lyon)
- Luca Motto Ros (Università di Torino, Turin
About the subject:
Classification has always been a central theme in mathematics. The study of Borel Reducibility of Equivalence Relations deals with the classification of points of standard Borel spaces up to equivalence relations by explicit, or Borel, mappings between such spaces.
This idea gives rise to a notion of complexity of equivalence relations, and tools from Descriptive Set Theory are used to compare such relations and measure their complexities.
The SGSLPS 2017 Spring meeting is organised by the Swiss Graduate Society for Logic and Philosophy of Science, SGSLPS
, with funding by the Swiss Academy of Sciences
The Swiss Graduate Society for Logic and Philosophy of Science (SGSLPS) is an association of advanced undergraduate and graduate students with a distinctive interest in the large domains of logic and philosophy of science
