Ultrafilters and Ultraproducts Across Mathematics and Related Topics
May 31 – June 6, 2020, Pisa, Italy

We are happy to announce the upcoming event “ULTRAMATH 2020 – Ultrafilters
and Ultraproducts Across Mathematics and Related Topics”, that will be
held in Pisa (Italy) from May 31st to June 6th 2020.

The international Conference “ULTRAMATH 2020” aims to present recent
results in the whole spectrum of mathematics which are grounded on the use
of ultrafilters and ultraproducts. Its main goals:

  • Disseminate information about the various techniques related to the use
    of ultrafilters and ultraproducts, and their potential to attack open
  • Bring together researchers with different backgrounds, and encourage
    their collaborations and interactions, especially on topics connecting
    different areas of mathematics.

The covered topics of UltraMath 2020 include (but are not limited to):

Additive and Combinatorial Number Theory.
Combinatorics and Ramsey Theory.
Algebra and Geometry.
General Topology.
Measure Theory.
Ergodic Theory and Dynamics.
Functional Analysis and Metric Spaces.
Nonstandard Analysis and Model Theory.
Generalized Spaces and Differential Equations.
Set Theory.

Greater prominence will be given to those results that satisfy (most of)
the following conditions:

  • The results can be formulated and presented in non-specialist terms, and
    be in principle understandable by any practicing mathematician.
  • The usage of ultrafilters/ultraproducts is important (or even essential)
    in obtaining these results.
  • The results connect different areas of mathematics.
  • The results reveal new facets of known important topics.

This is the second edition of ?UltraMath?, after the one held in Pisa in

Di Prisco Fest, Bogota

A conference in honour of Carlos di Prisco’s birthday will take plave at the Universidad de Los Andes, Bogota, Colombia, 27-29 Nov 2019.

Carlos di Prisco, who has been a supporter of the ASL’s activities for many years, will turn 70 years old in October 2019. This conference is held in honor of his life and work. It is intended for a wide audience, especially for students, but will also include the participation of mathematicians who have worked with Carlos and are close to him.

Please see the conference website:

Invited speakers include: J. Bagaria, C. Brech, J. Lopez-Abad, N. Dobrinen, A. Arias, and X. Caicedo. Members of the Organizing Committee: A. Villaveces, C. Uzcategui and J. Mijares.

Maître de conferences position, Reunion

A position as maître de conferences is opened in the University of Reunion (Indian Ocean, France).

Set theory and logic belongs to the priority areas.

The deadline is the 21/11/2019. The qualification of the French university system is needed to apply, so you need to have obtained this in the qualification round 2018-19 or before.

The salary of a maître de conferences in Reunion is 53% more than in the mainland of France.
