11th Young Set Theory Workshop, Lausanne

Dear all,

We are happy to announce that the 11th Young Set Theory Workshop will take place June 25-29 2018, at the Bernoulli Centre in Lausanne, Switzerland. 

The aims of the Young Set Theory workshops are to bring together young researchers in the domain of set theory and give them the opportunity to learn from each other and from experts in a friendly environment. A long-term objective of this series of workshops is to create and maintain a network of young set theorists and senior researchers, so as to establish working contacts and help disseminate knowledge in the field.

This year’s Young Set Theory workshop will take place at the end of the Descriptive set theory and Polish groups semester. While the organization of the workshop is independent of that of the semester, we hope the proximity will promote attendance of young researchers from extra-European countries.

It involves tutorials by established researchers as well as short (20 minute) presentations by PhD students, master students and first-year postdocs on their research.

We are happy to announce that the tenth edition of “PhDs in Logic” will take place in Prague, Czech Republic during 1st – 4th May 2018 at the Institute of Philosophy of the Czech Academy of Sciences.

The tutorial speakers are:

Chris Fermüller (TU Wien)
Radek Honzík (Charles University)
Jan Krají?ek (Czech Academy of Sciences)
Roman Kuznets (TU Wien)
Francesca Poggiolesi (Université Paris 1 Panthéon-Sorbonne)

Abstract submission:

PhD students, master students, and first-year postdocs in logic from
disciplines that include but are not limited to philosophy, mathematics,
and computer science are invited to submit an extended abstract on their
research. Submitted abstracts should be about 2 pages long (not including
references). Each abstract will be anonymously reviewed by the scientific
committee. The accepted abstracts will be presented by their authors in a
20 minute presentation during the conference. The deadline for abstract
submission is 19th January 2018. Please submit your blinded abstract via:

Call for nominations for the board of the ESTS

Dear members of the European Set Theory Society (ESTS),
a new board of the ESTS needs to be installed. Mirna Dzamonja and Istvan Juhasz intend to step down as board members. The current board proposes that Vera Fischer and ‘saf Rinot become new board members, that Boban Velickovic becomes the new president, and that Philip Welch becomes the new vice president. The other current board members (Jouko Väänänen as treasurer, Ralf Schindler as secretary, and Asger Tornquist) would be willing to continue their service on the board.
We would like to ask you to send us any potential further nominations for candidates to the board by December 01, 2017, by email to Istvan Juhasz <juhasz@renyi.hu> and Ralf Schindler <rds@wwu.de>.
Best regards, Ralf Schindler

On the Infinite

On the Infinite: An Interdisciplinary Symposium

Institute Henri Poincaré, October 18 – October 20, 2017 and Sorbonne October 21, 2017

Infinity: the break in the horizon, the “what cannot be counted”, boundless, bottomless, eternal, illimitable and absolute. The infinite encloses physical space; the infinite holds time within itself.

Already in the classical period, philosophers were undone by Zeno’s paradox, that an arrow shot from its bow will never reach its target because it must pass through every point between bow and target, and there are infinitely many such points. For cosmologists, the urgent question is: Is the universe finite or infinite? Will it last forever? And theologians saw in it an attribute of God, and were even prohibited to talk about it.

For the mathematician the infinite is the oil in the machine. For the mathematician who is a set theorist the infinite is a totality—completed, though in Aristotle’s sense, out of view; while at the same time the infinite is essentially open: open “above”, so numberless; but also open inwardly, in the way it copies itself internally over and over again, prints an image of itself into every one of its proper parts, and reprints, and reprints, and reprints, toward an endlessly fractured and ramified whole.

Critical conceptions of the infinite coming from outside of mathematics may coalesce around the concept of seriality. In The Infinite Line the art historian Briony Fer writes of the various serial strategies available to the artist; how “repetition, splintered into multiple registers, [is] no longer pitched against the aura of a single, unique artwork, so much as against its other selves.”

In this four-day interdisciplinary symposium we juxtapose lectures by set theorists and other mathematicians with those by art historians, architects, artists and philosophers, in an attempt to create a dialogue across cultures.

Some of the mathematical talks will be aimed at a general audience.

The symposium is accompanied by an exhibition of the work of the sculptor Fred Sandback.
