Streszczenie

Let $G$ be a locally compact group and let $\pi $ be a unitary representation. We study amenability and H-amenability of $\pi $ in terms of the weak closure of $(\pi \otimes \pi )(G)$ and factorization properties of associated coefficient subspaces (or subalgebras) in $B(G)$. By applying these results, we obtain some new characterizations of amenable groups.
