Annual Report 2005 - Fields Institute - University of Toronto

Workshop on Topological Strings
January 10-14, 2005.
Held at the Fields Institute
Organizers: Ezra Getzler (Northwestern), Kentaro Hori
(Toronto) and Sheldon Katz (Illinois/Urbana-Champaign)
Topological string theory is currently a very active field
of research for both mathematicians and physicists. In
mathematics, it leads to new relations between symplectic
topology, algebraic geometry and combinatorics. In physics,
it is a laboratory for the study of basic features of string
theory, such as background independence, open/closed
string duality, non-perturbative completion, as well as an
effective framework for computing spectra and interactions
in full-fledged string compactifications.
This workshop brought together a range of experts on different
aspects of topological string theory from both the
mathematics and physics communities. Twenty five lectures
were given over five days, to over seventy participants. The
workshop was held at the Fields Institute, as an activity in
the Geometry of String Theory program, sponsored jointly
by the Fields and Perimeter Institutes. Additional funding
was supplied by the US NSF, through a grant in support
of the participation of junior researchers in the thematic
program.
