The Banff International Research Station will host the "The SU(3) Casson invariant for spliced sums" workshop from June 19th to June 26th, 2011.

Roughly, the SU(3) Casson invariant is the count of flat SU(3) connections on a homology 3--sphere. In order to get a better understanding of this invariant under surgery, we want to prove a formula for spliced sums of torus knot complements.

The Banff International Research Station for Mathematical Innovation and Discovery (BIRS) is a collaborative Canada-US-Mexico venture that provides an environment for creative interaction as well as the exchange of ideas, knowledge, and methods within the Mathematical Sciences, with related disciplines and with industry. The research station is located at The Banff Centre in Alberta and is supported by Canada's Natural Science and Engineering Research Council (NSERC), the U.S. National Science Foundation (NSF), Alberta's Advanced Education and Technology, and Mexico's Consejo Nacional de Ciencia y Tecnología (CONACYT).
