Symposium of the Set Theoretic Pluralism network, Bristol, June 20-25

The second and final symposium of the Set Theoretic Pluralism (STP) network will take place at the University of Bristol on June 20-25, 2017. We would like to invite researchers from all relevant disciplines to attend the symposium, including set theory, philosophy of mathematics, metaphysics, philosophy of language, and epistemology.

The STP network draws together experts in mathematics and philosophy to grapple with the increasingly popular idea that mathematical reality may be best understood as fractured and indeterminate. Participants will include Sy David Friedman (Vienna), Peter Koellner (Harvard), Hugh Woodin (Harvard), Sean Walsh (UC Irvine), Toby Meadows (Queensland), Philip Welch (Bristol), Giorgio Venturi (Campinas), Carolin Antos (Vienna), Neil Barton (Vienna), Zeynep Soysal (Harvard), and Benedict Eastaugh (Bristol).

Registration for the symposium is now open (participation is free, but registration is required). The registration deadline is Monday 5 June, 2017.

To register, please email and include the following information:

* Name and affiliation.

* Whether you would like to attend the conference dinner, scheduled for Thursday 22 June, 2017. Places are limited and will be allocated on a first-come, first-served basis.

* Any dietary restrictions or preferences.

* Which days you plan to attend the symposium, if you are not attending the entire event.

Further details of the symposium, including the programme and details of the location, will be published on the symposium website:

The STP network is funded by a Leverhulme International Network grant and is hosted at the University of Bristol. The STP network partners include the University of Aberdeen, Harvard University, the University of Bristol, the University of Vienna, the University of Helsinki, and the University of California, Irvine.

Applications of model theory to operator algebras, Houston, July 31 – August 4

Dear Colleagues,

This is an announcement for an NSF-funded conference on “Applications
of Model Theory to Operator Algebras” to be held at the University of
Houston from July 31 — August 4, 2017. This conference will feature a
lecture series by our main speaker, Ilijas Farah, as well as several
plenary research talks by various experts in Operator Algebras and
Model Theory.

The purpose of this conference is two-fold: First, to serve as a
“master class” for non-experts and young researchers to learn about
fundamental concepts presented by Professor Ilijas Farah, a leading
expert and renowned expositor of these topics; and second, to inform
and update experts in other areas of operator algebras about the
latest advances and achievements of the subject. More information on
these talks, and the topics covered, can be found on the conference

We hope you will be able to attend.

Large Cardinals and Strong Logics: September 5 through December 16

Dear colleague,

We would like to inform you about the forthcoming CRM Intensive Research Program on Large Cardinals and Strong Logics, to be held from September 5 to December 16, 2016.

The National Science Foundation and the Association for Symbolic Logic offer grants to participate in the program and its scientific events. You can check the program’s web page for further information at


Many natural mathematical concepts cannot be expressed in first-order logic but need stronger logics. Among such concepts are the freeness of a group, separability of a space, completeness of an order, etc. By a strong logic we mean model-theoretically defined extensions of first-order logic, such as first-order logic with generalized quantifiers, infinitary logics, second-order logic, as well as higher-order logics. The study of strong logics runs immediately into questions that depend essentially on set-theoretical assumptions beyond the standard ZFC axioms, such as infinitary combinatorial principles and the existence of large cardinals. It is therefore crucial to be able to pinpoint the position of a given strong logic in the set-theoretical definability hierarchy, thus helping us understand better the set-theoretical nature of the logic, and therefore of the mathematical notions it can express.


This program will bring to the CRM a diverse group of international high-level researchers working in strong logics, large cardinals, the foundations of set theory, and the applications of set-theoretical methods in other areas of mathematics, such as algebra, set-theoretical topology, category theory, algebraic topology, homotopy theory, C*-algebras, measure theory, etc. In all these areas there are not only direct set-theoretical applications but also new results and methods, which are amenable to the expressive power of strong logics.

During the Research Program the following activities will be held:

Advanced Course on Large Cardinals and Strong Logics, from September 19 to 23, 2016.
Deadline for registration: August 1st, 2016. More information on registration and grants available at

Workshop 1: Set-theoretical aspects of the model theory of strong logics, from September 26 to 30, 2016.
Deadline for registration: August 1st, 2016. More information on registration and grants available at

Young researcher’s Seminar week, from November 7 to 11, 2016.
You can participate by presenting your work before October 31, 2016.
More information on how to participate at’s-Seminar-week.aspx

Workshop 2: Applications of strong logics in other areas of mathematics, from November 14 to 18, 2016.
Deadline for registration: November 6, 2016. More information on registration and grants available at Note: This workshop will take place in Barcelona, in the old University of Barcelona building (not in Bellaterra).

Please, feel free to distribute this information among your colleagues.

We hope you find this information useful and look forward to hosting you at the CRM.
