Honorary Presidents of the ESTS

The Board of Trustees of the European Set Theory Society decided at its recent meeting in Cambridge that it would be appropriate to honour one or more set theorists with the title of Honorary President of the Society.

The intention was to designate a set theorist or theorists whose work has particularly distinguished the field and contributed to its significant advancement over their career.

The Board unanimously voiced its approval of the suggestion that

András Hajnal (Budapest), Ronald Jensen (Berlin), and Azriel Lévy (Jerusalem)

be approached and asked if they accept this honour. We are delighted to inform the members of the Society that all the three of them have accepted our offer.

Hausdorff medal 2015

The second Hausdorff medal was awarded by the European Set Theory Society on August 26, 2015, at the fifth European Set Theory Conference, held at the Isaac Newton Institute in Cambridge, to Ronald Jensen (Humboldt University, Berlin) and John Steel (UC Berkeley) for their work K without the measurable.

Statement read by the president of the European Set Theory Society, Istvan Juhasz, at the award ceremony:

Ladies and gentlemen, dear friends and colleagues!

It is my pleasure and privilege, as president of the European Set Theory Society, to announce the winner of the Hausdorff medal. This is awarded by the Board of Trustees of the European Set Theory Society at the biennial European Set Theory Conference for the most influential published work in set theory in the last five years.

Nominations for the Hausdorff medal 2015 were solicited from the members of the Society last fall. Five very worthy nominations were deliberated by the prize committee which consisted of the Board of Trustees augmented with the winner of the previous medal, Hugh Woodin.

After long and serious discussion the unanimous decision was reached that the second Hausdorff medal is awarded to the paper

K without the measurable, The Journal of Symbolic Logic, Volume 78, Issue 3 (2013), 708-734

by Ronald Jensen and John Steel.

Before handing over the medals and the diplomas that go with them to the winners, please allow me to briefly review the winning work.

The construction of core models originates in the seminal work of Dodd and Jensen of just about 40 years ago. Since that time the constructions have been vastly developed and the machinery in its various incarnations is the main tool for showing the necessity of large cardinals for independence proofs. Even more striking is the use of core model methods to prove outright implications of, for example, of determinacy.

Despite all this progress, an absolutely fundamental question remained unresolved. What is the strongest core model which can be constructed just in ZFC? More precisely, suppose there is no inner model with a Woodin cardinal; does then K exist? Jensen and Steel solved this problem in the paper K without the measurable.

The Jensen-Steel construction of K is best possible (having been done just within ZFC) and is therefore a seminal milestone in the entire subject of core models and inner model theory. It marks in some sense the conclusion of a line of investigation which began with Jensen’s Covering Lemma.

It already has many applications, for example as a corollary of their construction, one obtains the equiconsistency of ‘ZFC + There is a saturated ideal on \omega_1’ with ‘ZFC + There is a Woodin cardinal’.

Position as Maitre de conférence in mathematical logic, Paris (France), Deadline: 23 Oct 2014

There is going to be an opening for a Maitre de Conférence position (Assistant Professor)
in Mathematical Logic at the University of Paris 7 in 2015. The hiring procedure in France
requires candidates to go through a qualification procedure. This procedure is done
by the CNU (ministry committee). More information can be found on the website of
the section 25 (mathematics) of the CNU

http://cnu25.emath.fr/qualif/index.html

In order to initiate the procedure the candidates should create an account on the website

https://galaxie.enseignementsup-recherche.gouv.fr/antares/can/index.jsp

The deadline for this is October 23 2014. Each candidate will then be assigned two referees
and should then send his/her cv, publications, etc to them. This should be done by
December 19 2014. The qualification will be decided in late January/early February.
The qualification is valid for 4 years. Open positions will be announced in early March 2015.

ESTS is associate member of the EMS

Dear members,
 
I am pleased to inform you that our society has been accepted as an associate member of the European Mathematical Society, rubbing shoulders with the likes of the London Mathematical Society and Société Mathématique de France. I suppose that the website http://www.euro-math-soc.eu/member-societies.html will be updated soon. We seem to be the among rare societies which does not correspond to a country, but to a mathematical subject! Best wishes to all, Mirna 
 
Mirna Dzamonja, President ESTS

Hausdorff Medal

The Hausdorff medal was awarded to Hugh Woodin at the fourth European Set Theory Conference on July 15. 

The Hausdorff medal is awarded by the European Set Theory Society to the most influential published work in set theory in the last five years. This is the first time that the medal is awarded. 

Statement read by the President of the European Set Theory Society, Mirna Dzamonja, at the Award ceremony:

Nominations for the Hausdorff medal 2013 were solicited from the members of the Society in November 2012.

The Board of Trustees deliberated taking into account the goal of the Hausdorff medal of ESTS, which is to award the most influential published work in set theory in the last five years. After considering several very worthy candidates our attention became focused on one particular body of work, consisting of the following papers:

  • Woodin, W. Hugh Suitable extender models I. J. Math. Log. 10 (2010), no. 1-2, pp.101–339.
  • Woodin, W. Hugh Suitable extender models II: beyond \omega-huge. J. Math. Log. 11 (2011), no. 2, pp.115–436.

where the author made a major contribution to the inner model theory of supercompact cardinals and beyond.

This work is innovative, courageous and deep, and no matter what the final solution of this major problem in set theory will look like, it is clear that it will have to depend on the contributions Woodin made in these papers.

Dear collegues, the winner of the first Hausdorff medal of the European Set Theory Society, setting a very high level for the future winners, is Hugh Woodin of the University of Berkeley, California.
