Outline of Scientific Activities

The semester will starts with a week-long summer school. The activities during the summer school include mini-courses and lectures designed to prepare the students and other participants for the semester.


The program will also include a weekly seminar. This will be a continuation of the weekly Toronto Set Theory seminar, currently meeting at the Fields Institute

Graduate courses
(starting the week of Sept. 17)

Course on Forcing
Alan Dow
(UNC Charlotte)

Tuesdays and Thursdays 11:00 a.m. - 12:30 p.m.
Stewart Library
This will be a basic Forcing course directed towards graduate students and non-experts which will still reach a reasonable level of sophistication in designing forcing notions. An emphasis will be placed on examples and on the methodology of designing the forcings themselves rather than the formal and rigorous development of the logical underpinnings of forcing.

New -Updated notes for the course for Sept 25 and Sept 27
Paper on discussion about the Kunen and Miller results for the Cohen model.
Notes from October 2

Course on Large Cardinals

Paul Larson (Miami University)

Tentatively Tuesdays and Thursdays 1:30 p.m. - 3:00 p.m.
Stewart Library
Large cardinal axioms, also known as the axioms of the higher infinite, posit cardinals that prescribe their own transcendence over smaller cardinals and provide a superstructure for the analysis of strong propositions in set theory. They form an essentially linear hierarchy reaching up to inconsistent extensions of motivating concepts. This course will focus on the most fundamental large cardinal notions, emphasizing their inter-relationship with combinatorics and with forcing techniques.

Taking the Institute's Courses for Credit
As graduate students at any of the Institute's University Partners, you may discuss the possibility of obtaining a credit for one or more courses in this series with your home university graduate officer and the course instructor. Assigned reading and related projects may be arranged for the benefit of students requiring these courses for credit.


September 8-9, 2012
Appalachian Set Theory Workshop
C*-algebras, classification and descriptive set theory
Fields Institute

September 10-14, 2012
Workshop on Applications to Operator Algebras

Organizers: Ilijas Farah, Andrew Toms, Alexander S. Kechris
This workshop will explore connections between set theory and C*-algebras, as well as the emerging connections with von Neumann algebras. Some long-standing problems from the theory of C*-algebras were recently solved by using increasingly sophisticated set-theoretic tools. Emphasis will be put on applications of forcing to still unsolved problems, such as the general Stone-Weierstrass problem or the consistency of a positive answer to Naimark's problem. Part of the workshop will be devoted to the emerging connections between the classication problems in operator algebras and the abstract classication program in descriptive set theory.

October 22-26, 2012
Workshop on Forcing Axioms and their Applications.
Organizers: Jordi Lopez Abad, Justin Tatch Moore, Stevo Todorcevic
This workshop will bring together researchers working on combinatorial analysis of Banach spaces and those specializing in forcing axioms. Central to the discussion will be combinatorial consequences of Martin's Maximum which are driven by applications and which are readily accessible to those working in analysis and other fields. The driving goal will be to progress our understanding in well known open problems in the the theory of Banach space such as the metrization problem for compact convex sets, the smooth bump problem, and the separable quotient problem.

November 12-16, 2012
Workshop on Iterated Forcing and Large Cardinals

Organizers: Michal Hrusak, Paul Larson, Saharon Shelah, W. Hugh Woodin
This workshop will focus on preservation theorems for iterated forcing constructions. The goal is to better understand when iterated forcing constructions preserve the Continuum Hypothesis and its strengthenings and also certain inequalities of cardinal invariants of the continuum. An additional focus will be to attempt to better understand the relationship between Woodin's Pmax-machinery and more conventional iterated forcing constructions. Work of Shelah and Woodin already hints that large cardinals will likely play a role in studying when reals are added in iterated forcing constructions.

Distinguished and Coxeter Lecturers

November 7-9, 2012,
Distinguished Lecture Series

Matthew D. Foreman, University of California, Irvine

Postdoctoral Fellows and Program Visitors

The Thematic Program on Forcing and its Applications is pleased to welcome the following Postdoctoral Fellows to the Program.

All scientific events are open to the mathematical sciences community. Visitors who areinterested in office space or funding are requested to apply by filling out the application form (now closed). Additional support is available (pending NSF funding) to support junior US visitors to this program.
Fields scientific programs are devoted to research in the mathematical sciences, and enhanced graduate and post-doctoral training opportunities. Part of the mandate of the Institute is to broaden and enlarge the community, and to encourage the participation of women and members of visible minority groups in our scientific programs.
