<P><BR>Title: Reflexivity and hyperreflexivity of bounded $n$-cocycle spaces <BR>and application to convolution<BR>operators<BR><BR>Abstract: We introduced the concept of strong property $\mathbb{B}$ with <BR>a constant for Banach algebras and, by applying certain analysis on the <BR>Fourier algebra of a unit circle, we show that all C$^*$-algebras and <BR>group algebras have the strong property $\mathbb{B}$ with a constant <BR>given by $288\pi(1+\sqrt{2})$. We then use this result to find a <BR>concrete upper bound for the hyperreflexivity constant of certain spaces <BR>of bounded $n$-cocycles from $A$ into $X$, where $A$ is a C$^*$-algebra <BR>or the group algebra of a group with an open subgroup of polynomial <BR>growth and $X$ is a Banach $A$-bimodule. As another application, we show <BR>that for a locally compact amenable group $G$ and $1<p<\infty$, the <BR>space $CV_P(G)$ of convolution operators on $L^p(G)$ are hyperreflexive <BR>with a constant given by $288\pi(1+\sqrt{2})$. This is the <BR>generalization of a well-known result of E. Christiensen for $p=2$.<BR><BR>This is a joint work with Jafar Soltani Farsani.<BR></P><BR><BR>
