Laurent phenomenon algebras arising from surfaces
arXiv:1608.04794
Abstract
It was shown by Fomin, Shapiro and Thurston that some cluster algebras arise from orientable surfaces. Subsequently, Dupont and Palesi extended this construction to non-orientable surfaces. We link this framework to Lam and Pylyavskyy's Laurent phenomenon algebras, showing that both orientable and non-orientable unpunctured marked surfaces have an associated LP-algebra.
