$p$-Fourier algebras on compact groups
Abstract
Let be a compact group. For we introduce a class of Banach function algebras on which are the Fourier algebras in the case , and for are certain algebras discovered in \cite{forrestss1}. In the case we find that if and only if and are isomorphic compact groups. These algebras admit natural operator space structures, and also weighted versions, which we call -Beurling-Fourier algebras. We study various amenability and operator amenability properties, Arens regularity and representability as operator algebras. For a connected Lie and , our techniques of estimation of when certain -Beurling-Fourier algebras are operator algebras rely more on the fine structure of , than in the case . We also study restrictions to subgroups. In the case that , restrict to a torus and obtain some exotic algebras of Laurent series. We study amenability properties of these new algebras, as well.
