Centre for Particle Theory Colloquia: "A mathematical bridge between quasicrystals, fullerenes and virus structures: novel approaches to open problems in virology."
29 April 2003 00:00 in CLC 202
"We implement mathematical techniques developed for the study of quasicrystals and fullerenes to address open problems in virology. In particular, we use tiling theory (a theory that considers tessellations of surfaces by a set of basic shapes) to explain the location of the protein subunits in the viral capsids, that is in the protein shells protecting the viral genome. We furthermore show how affine extensions of noncrystallographic Coxeter groups can be used to obtain shell models for the packing of the viral genome. Finally, we point out an intriguing connection between the geometry of fullerenes, viral capsids and Skyrmions. The presentation will be elementary, and will not require any previous knowledge in any of the above areas.
