## Summer school and conference on affine Schubert calculus at Fields

‘Affine Schubert Calculus’ refers to an extension of Schubert calculus to affine Grassmannians and affine flag varieties. The new approach to affine Schubert calculus is made possible by the recent discovery of certain explicitly defined symmetric functions called k-Schur functions. The k-Schur functions, which arose in the study of the seemingly unrelated Macdonald theory, were recently shown to be connected to the geometry and topology of the affine Grassmanian.

This event consists of a summer school and workshop to be held at Fields Institute over a nine day period. The period July 7-10 will be dedicated to the summer school, with July 11 as a free day and followed by another 4 days of workshop that will consist of contributed talks. The purpose of the summer school is to highlight some of the major developments of the Affine Schubert Calculus related to k-Schur functions with survey presentations and tutorials. The workshop portion of the event will highlight some recent related research.

## Summer school on the Hitchin fibration

I found out about this summer school from Steve Kudla’s door. The Hitchin fibration is an important topic of current research, related to the geometric Langlands program.

- Representations of quantum groups and crystal bases,
- Representations of affine Lie algebras,
- Representations of Lie algerbas in positive characteristic,
- Representations of affine Hecke algebras,
- Modular or ordinary representations of finite reductive groups,
- Representations of complex reflection groups and associated Hecke algebras.

The (tentatively) confirmed speakers, as of October 2010, are

T. Arakawa (Nara Women's University)
S. Ariki (RIMS)
R. Bezrukavnikov (MIT)
J. Brundan (University of Oregon)
P. Fiebig (Freiburg Univesity)

## Taipei conference 2010

“Taipei Conference on Representation Theory” in Academia Sinica, Taipei, Taiwan, December 19-23, 2010.

## Grad student geometry-topology conference (U Michigan, April 2010)

8th annual Graduate Student Topology and Geometry Conference will take place April 10-11, 2010 at the University of Michigan, Ann Arbor.

The theme(s) of the student conference are quite broad, but the two plenary speakers are

-Alan Reid (UT Austin)
-Doug Ravenel (University of Rochester).

In addition, there will be 3 “problem/open-question sessions” with the junior speakers

- Moon Duchin (UMichigan),
- Benjamin Schmidt (Michigan State University)
- Tom Fiore (UMichigan, Dearborn),

on geometric group theory, differential geometry, and homotopy theory. Finally, and most importantly, there will be a large number of 30-minute graduate student talks, ranging in style from the expository to the mini-research talk.

## Workshop on Lie Theory and its Applications in Ottawa

I'm going to this next weekend.

Workshop on  Lie Theory
and its Applications  will  be held at  Carleton University, Ottawa,
February 26-28, 2010. This Workshop is sponsored by the Fields Institute.

The web-page for the Workshop is:
http://www.fields.utoronto.ca/programs/scientific/09-10/lietheory/

Keynote speakers:
Roman Bezrukavnikov (MIT) [to be confirmed]
Jonathan Brundon  (Oregon)

We plan to have approximately 12 one-hour talks at this Workshop. We will
follow an  Oberwolfach approach - apart  from  the Keynote speakers,  the
rest of the programme will be specified only during the Workshop.

## Connections in Geometry and Physics in Waterloo

I will be going to this on.

“Connections in Geometry and Physics”,

To be held on 7-9 May, 2010, at the Perimeter Institute for Theoretical Physics, in Waterloo, Ontario, Canada.

The objective of the workshop is to bring together researchers who work at the interface between geometry and physics. The first meeting of the workshop was held in May 2009, to great success, and the talks covered topics from geometric analysis, moduli space theory, and symplectic geometry. In 2010, we plan to focus on the following main areas: mathematical general relativity, gauge theory, and mirror symmetry.

## Workshop on Operator Algebras and Conformal Field Theory

This is a first announcement for a workshop that explores the foundations of
conformal field theory from the perspective of operator algebras.  The
workshop will be led by Andre Henriques and held at the University of
Oregon, from 16 August through 21 August 2010.  It will be completely
expositional, and aimed at graduate students and postdocs.  There will be a
strong emphasis on student participation, as in the case of the annual
Talbot Workshops at MIT.  Further information appears below, as well as on
the web:
