Spin state sum models in two dimensions
Gomes Tavares, Sara Oriana (2015) Spin state sum models in two dimensions. PhD thesis, University of Nottingham.
We propose a new type of state sum model for two-dimensional surfaces that takes into account topology and spin. The definition used - new to the literature - provides a rich class of extended models called spin models. Both examples and general properties are studied. Most prominently, we find this type of model can depend on a surface spin structure through parity alone and we explore explicit cases that feature this behaviour.
