*G*is compact if and only if its convolution algebra has a non-zero (weakly) compact multiplier. Dually,

*G*is discrete if and only if its Fourier algebra has a non-zero (weakly) compact multiplier. In addition,

*G*is compact (respectively, amenable) if and only if the second dual of its convolution algebra equipped with the first Arens product has a non-zero (weakly) compact...

*T*, which acts on some separable complex infinite dimensional Hilbert space, is said to be $$*$$ ∗ -amenable if the $$C^*$$ C ∗ -algebra generated by

*T*is amenable. In the present paper, the stability of $$*$$ ∗ -amenability under similarity is studied. It is proved that each operator similar to

*T*is $$*$$ ∗ -amenable if and only...

*A*of discrete semigroup

*S*called

*A*-amenable is introduced and studied. This concept is characterized by several equivalent statements which are analogues of properties characterizing left amenable semigroups. We also obtain the relationship between this version of amenability and Følner’s condition.

*G*, we show that the operator ultra-amenability of

*A*(

*G*) imposes severe restrictions on

*G*. In particular, it forces

*G*to be a discrete, amenable group with no infinite abelian subgroups. For various classes of such...
