On Invariant Means which are Not Inverse Invariant

open access: yesCanadian Journal of Mathematics, 1968
In (1) R. G. Douglas says: “For a finite abelian group there exists a unique invariant mean which must be inversion invariant. For an infinite torsion abelian group it is not clear what the situation is.” It is not hard to see that if every element of an abelian group G is of order 2, then every invariant mean on G is also inversion invariant (see 1 ...

On the Set of Invariant Means

Journal of the London Mathematical Society, 1988
Adapting a technique used by \textit{C. Chou} [Trans. Am. Math. Soc. 273, 207-229 (1982; Zbl 0507.22007)] which consists in embedding a large set into the set of all invariant means, the author establishes the following theorem: If G is a locally compact noncompact amenable group, then the set of all topological invariant, inversion invariant means on \
