"Arens Regularity of Ideals in $A(G), A_{cb}(G)$,  and $A_M(G)$"

The Fourier algebra $A(G)$ is well-known to be the predual of the group von Neumann algebra $VN(G)$, and hence has a natural operator space structure. The closure of $A(G)$ in the multiplier and completely bounded multipliers is denoted $A_M(G)$ and $A_{cb}(G)$ respectively. In this talk we will discuss topologically invariant means and Arensregularity of ideals in these algebras, which is based on joint work with Brian Forrest and Aasaimani Thamizhazhagan.
