Symplectic Geometry and Hamiltonian Group Actions
Held in conjunction with the program on Infinite-Dimensional Lie Theory and Its Applications and the program on Symplectic Topology, Geometry and Gauge Theory.

Start Date: week of January 15, 2001
Location: Room 210 or 230 at the Fields Institute
A symplectic manifold (a manifold equipped with a nondegenerate closed two-form) is the natural mathematical generalization of the phase space considered in classical machanics. Hamiltonian group actions are a special case of Hamiltonian flows, which are a natural generalization of Hamilton's equations. Coadjoint orbits are natural examples of symplectic manifolds equipped with Hamiltonian group actions. The course treats the following topics:
- Moment maps; symplectic quotients
- The symplectic structure on coadjoint orbits
- The Atiyah-Guillemin-Sternberg convexity theorem
- Delzant's theorem and introduction to toric geometry from the synthetic point of view
- Geometric quantization: applications to representation theory (survey)
- Equivariant cohomology and applications to symplectic geometry: (a) the localization theorem of Berline-Vergne, the Duistermaat-Heckman theorem, (b) Recent results on cohomology rings of symplectic quotients, obtained using localization (survey)
- An infinite dimensional symplectic quotient: the moduli space of flat connections on a Riemann surface (following Atiyah-Bott 1982 and Goldman 1984)

Moduli Spaces of Flat Connections
Held in conjunction with the Program on Symplectic Topology, Geometry and Gauge Theory.
Instructor: E.Meinrenken, University of Toronto
Time: Tuesdays and Thursdays 1:30 - 3 pm
Start Date: January 16, 2001
Location: Room 210 or 230 at the Fields Institute
Moduli Spaces of flat connections on 2-manifolds are encountered in areas so diverse as Algebraic Geometry, Representation Theory, Knot Theory, Quantum Cohomology, and Conformal Field Theory. In this course we will give an overview from the perspective of Symplectic Geometry and (to a lesser extent) Mathematical Physics. Among other things, we will describe fixed point formulas for loop group actions which imply formulas for volumes, intersection pairings, and quantum dimensions of the moduli spaces.
Topics to be covered include:
- Connections, Curvature and Holonomy
- Gauge Theory construction of moduli spaces
- Holonomy description of moduli spaces
- Hamiltonian loop group actions
- Witten's volume formulas, intersection pairings
- Verlinde dimension formulas

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 lecture 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.Financial Assistance
As part of the Affiliation agreement with some Canadian Universities, graduate students are eligible to apply for financial assistance to attend graduate courses. Two types of support are available:- Students outside the greater Toronto area may apply for travel support. Please submit a proposed budget outlining expected costs if public transit is involved, otherwise a mileage rate is used to reimburse travel costs. We recommend that groups coming from one university travel together, or arrange for car pooling (or car rental if applicable).
- Students outside the commuting distance of Toronto may submit an application for a term fellowship. Support is offered up to $1000 per month. Send an application letter, curriculum vitae and letter of reference from a thesis advisor to the Director, Attn.: Course Registration, The Fields Institute, 222 College Street, Toronto, Ontario, M5T 3J1.
Applications for financial support should be received by the following deadlines: April 15, 2000 for the Fall term and September 15, 2000 for the Winter term.
