SUMMARY:Fermionic quantization of knot solitons - Speight\, M (University 
 of Leeds)

DESCRIPTION:Knot solitons arise as global energy minimizers in field theor
 ies such as the Faddeev-Skyrme model. Such field theories\, when quantized
 \, are inherently bosonic because the fundamental fields represent scalar 
 bosons. Nonetheless\, the solitons they support can be given fermionic exc
 hange statistics\, provided the classical field configuration space has th
 e right algebraic topology. In this talk I will review a computation of th
 e fundamental group of the Faddeev-Skyrme configuration space\, and show h
 ow this allows a consistent fermionic quantization of knot solitons. This 
 is based on (separate) collaborations with Dave Auckly and Steffen Krusch.
