Set theory, logic and Ramsey theory

October 16, 2017

José G. Mijares and I are organizing a special session at the 2018 Joint Mathematics Meetings in San Diego, cosponsored by the AMS and the ASL, on Set theory, logic and Ramsey theory. The session will take place the morning of Wednesday January 10 and the morning and afternoon of Thursday January 11. See here for the schedule and additional details. I transcribe the schedule below:


Bogotá, September 17-20, 2014, 50 años carrera de matemáticas, Universidad de los Andes

September 17, 2016

I ran last night into the Flickr page for this conference essentially by accident. Couldn’t find who to credit for this picture.

The picture will appear in the book of proceedings of the Woodin conference, (Thanks to David Schrittesser for allowing us to use it.)

I’m sad I had to miss the meeting, although it was for obvious reasons.

BEST 2015

March 12, 2015


DATE:     June 15 – 17, 2015
WHERE: San Francisco State University

The 22-nd annual meeting of BEST will be hosted at San Francisco State University as a symposium of the 96th annual meeting of the American Association for the Advancement of Science – Pacific Division (AAAS-PD). Contributed and invited talks at BEST will be held on Monday, Tuesday and Wednesday.

In addition to invited speakers, the conference program has reserved speaking slots for students, post docs and pre-tenure tenure track faculty. NSF supported funding to assist up to ten student speakers, four post-doc speakers and two pre-tenure tenure track faculty speakers is available. For details on applying to the BEST program committee for these, please visit the conference website. In addition, the AAAS-PD provides up to $150 in travel funding for students. Please see the BEST conference website for more details on these also. There are a number of deadlines associated with applications for a travel grant.

Currently confirmed plenary speakers for BEST 2015 are:

  • Dr. Rodrigo Dias, University of Sao Paulo, Brazil
  • Dr. Mirna Dzamonja, East Anglia University, U.K.
  • Dr. Aleksandra Kwiatkowska, UCLA
  • Dr. Spencer Unger, UCLA
  • Dr. Trevor Wilson, Miami University, OH

Special features of BEST 2015 include:

In addition to the BEST symposium there are several other symposia and workshops of interest offered at the AAAS-PD annual meeting. On Monday, June 15, the AAAS-PD organized an evening at the California Academy of Sciences on Tuesday, June 16, the AAAS-PD hosts a banquet at which awards of excellence are given to student speakers selected by a panel of judges.

Student, post-doc and pre-tenure tenure track speakers are strongly encouraged to apply to BEST for an NSF-funded travel award. The travel expenses (airfare and lodging) of awarded speakers will be reimbursed up to the maximum amount of the award, and registration fees of awardees will be reimbursed.


BEST seeks to promote student participation in the conference via short (20 minute) presentations. To this end there are ten (10) NSF funded BEST travel awards  available for students. To apply for one of these awards, please follow the instructions given at the BEST website.

In addition to the BEST travel awards, up to 20 travel awards of up to $150 each are also available from the AAAS-PD to help students (including students participating in BEST) defray travel expenses to participate in the AAAS-PD annual meeting. Winners of these AAAS-PD travel awards will be announced at the AAAS-PD student award banquet. Student participants will be guests at this banquet.


BEST also seeks to be a forum for early career set theoretic scholars. In particular there are NSF funded BEST travel awards available for post-docs, and for pre-tenure tenure track faculty. To apply for one of these awards, please follow the instructions given at the BEST website.


The BEST schedule will also have a number of slots for 25 minute contributed talks. Anyone wishing to speak at BEST 2015 should submit an abstract as soon as possible (preferably prior to April 05) at the abstract submission site. It is strongly recommended to also contact one of the organizers as soon as possible to indicate interest/intention in presenting a talk  at BEST 2015.

Important deadlines:

DEADLINE 1: REGISTRATION: Please consult for registration costs and
deadlines. Registration fees depend on date of registration. We kindly request that Ph.D. mathematicians planning to participate in BEST 2015 consider acting as judges for the student presentations. The registration form has a place where willingness to act as a judge can be indicated.

There are also a number of excursions available that can be indicated on the registration form. Also consider attending the awards banquet in support of our student speakers – meal choices are available on the registration form.

DEADLINE 2: ABSTRACTS: Atlas Conferences, Inc. is providing abstract services for BEST 2015. Abstracts submitted by April 1 will appear in the proceedings of the annual conference of the AAAS-PD. See here for details on abstract submission.

DEADLINE 3: TRAVEL GRANTS: Presenting students, post-docs or pre-tenure tenure track faculty, please complete the application process to BEST by May 15. See the BEST 2015 website for details. Students, the deadline for the AAAS-PD student travel grants is May 1, 5:00 p.m. Pacific time.

Cryptic marks

February 5, 2015

New scientist recently ran a series on articles on “How to think about…” One of them, by Richard Webb and published December 13, 2014, was about infinity. It contains this quote:

Woodin’s notepads consist mainly of cryptic marks he uses to focus his attention, to the occasional consternation of fellow plane passengers. “If they don’t try to change seats they ask me if I’m an artist,” he says.

David Roberts wondered on Google+ what these cryptic marks look like. This reminded me of some pictures I took of them at the Conference on inner model theory at UC Berkeley last year.
