Center Of the Goldman algebra
arXiv:1412.2331 · doi:10.2140/agt.2016.16.2839
Abstract
We show that the center of the Goldman algebra associated to a closed oriented hyperbolic surface is trivial. For a hyperbolic surface of finite type with nonempty boundary, the center consists of closed curves which are homotopic to boundary components or punctures.
