This is an announcement of the forthcoming thematic semester on Descriptive Set Theory and Polish Groups that will take place at the Bernoulli Center in Lausanne, Switzerland, from January 1st to June 30th, 2018.

The focus of the semester will be on Descriptive Set Theory and Polish Groups along with applications in other branches of mathematics. While there will be continuous activity at the center throughout the semester, three conferences and two additional workshops will provide the main events. The themes of these will be

Borel combinatorics and ergodic theory
Structure and dynamics of Polish groups
Descriptive set theory
Ideals and exceptional sets in Polish spaces
Large scale geometry of Polish groups

First announcement: 6TH EUROPEAN SET THEORY CONFERENCE, Budapest, Hungary

Dear Colleague,

We are pleased to announce the 6th European Set Theory Conference (6ESTC) organized by the European Set Theory Society and the Alfréd Rényi Institute of Mathematics of the Hungarian Academy of Sciences.

July 3 - 7, 2017. (Date of arrival: July 2, date of departure: July 8.)

Alfréd Rényi Institute of Mathematics [] (Reáltanoda utca 13-15, 1053, Budapest, Hungary)

Homepage of the meeting:

Registration is now open at the Registration [] page of the above homepage of the meeting.

Registration fee:
65 000 HUF (approx. 210 EUR, if payment is received until April 15, 2017)

100 000 HUF (approx. 322 EUR, if payed at the conference venue) 

We are pleased to announce that 6ESTC is officially sponsored by the
Association for Symbolic Logic (ASL), hence student ASL members wishing to attend the meeting may apply for ASL travel funds.

Discount for students and fresh PhD's:
We are making an effort to secure funds to provide a discount from
the registration fee for a limited number of students and fresh PhD's. Unfortunately, it may happen that these funds only arrive so late, if at all, that this discount will be paid off as a refund at or after the conference. Please let us know on the registration form if you intend to apply for such a discount.

This Saturday is the Appalachian Set Theory workshop at CMU with Maryanthe Malliaris,
(I'll be attending.)

Meanwhile, the next meeting has been announced. From James Cummings:

An Appalachian Set Theory workshop will take place at Carnegie Mellon University on Saturday January 21 2017. Benjamin Miller will lead a workshop on "Applications of the open graph dichotomy".

For details please see the workshop web page at

Some support is available to cover travel and lodging expenses, the web page has details about how to apply.

The Appalachian Set Theory workshop series is supported by the National Science Foundation.

Here's Round 2 of my analysis: Are women becoming better represented over time as speakers at the ASL Annual Meetings?
The question I've been asked most since my first post is whether women have become better represented among ASL speakers over time. I'll try to answer it today for the Annual Meetings. Here are the factors I'm taking into acc...

Our paper on the rearrangement number is now out. The rearrangement number is the smallest number of permutations, which can successfully test any convergent series for absolute convergence, in the sense that any series that remains convergent to the same sum after all such rearrangements in the family is absolutely convergent.

The Royal Society is opening up its entire journal archive. What's the catch? It's doing so only until November 6th. So if you're burning to look something up, now you can. But if you just feel like a browse on November 7th, then that won't be possible. Is it ungrateful of me that my immediate reaction to initiatives like this is to feel that it is deeply wrong that they are "initiatives" rather than simply being the norm?

On a related topic, yesterday I heard an amazing performance of The Rite of Spring, arranged for organ duet -- that is, one organ and two organists. Again there is a catch, which is that the concert was illegal: Stravinsky's publishers, Boosey and Hawkes, do not allow the piece to be performed except in one of Stravinsky's two arrangements -- the one for orchestra and the one for piano duet. Stravinsky died 45 years ago in a very different era -- it feels very wrong that his publishers should have that kind of say over what can be done with his music.

Newest meeting analysis: the AMS/ASL meetings! There is far less of a trend apparent for these.
Today I'm going to try to answer the same question for the AMS/ASL meetings that I answered on Saturday for the Annual Meetings: how has the representation of women among speakers changed over time? I'm considering the same f...

It's always interesting to learn about what other mathematicians' experiences have been like. This is a 37-minute interview of the famous analytic number theorist Roger Heath-Brown by Ben Green, who draws him out with a great set of questions. Recommended if you have the time to spare.
