Abstract

We show that the amenability of a locally compact group GG is equivalent to a factorization property of VN(G)VN(G) which is given by VN(G)=<VN(G)VN(G)> VN(G) = <VN(G)^*VN(G)>. This answer partially two problems proposed by Z. Hu and M. Neufang in their article \textit{Distinguishing properties of Arens irregularity}, Proc. Amer. Math. Soc. 137 (2009), no. 5, 1753-1761.
