Recently we have shown a structure theorem for locally compact groups of polynomial growth. We give now some applications on various growth functions and relations to FC-G - series. In addition, we show some results on related classes of groups.

We show that a compactly generated locally compact group of polynomial growth having no non-trivial compact normal subgroups can be embedded as a co-compact subgroup into a semidirect product of a connected, simply connected, nilpotent Lie group and

If G is a locally compact group, then for each derivation D from L 1 (G) into L 1 (G) there is a bounded measure μ ∈ M(G) with D(a )= a ∗ μ − μ ∗ a for a ∈ L 1 (G) (“derivation problem” of B. E. Johnson).

For a discrete group G with Fourier algebra A(G), we study the topological centre $Z_t$ of the bidual. If G is amenable, then $Z_t$ = A(G). But if G contains a non-abelian free group $F_r$, we show that $Z_t$ is strictly larger than A(G). Furthermore

The Ghahramani–Lau conjecture is established; in other words, the measure algebra of every locally compact group is strongly Arens irregular. To this end, we introduce and study certain new classes of measures (called approximately invariant, respe

In this note we consider multi-dimensional Hartman almost periodic functions and sequences, defined with respect to different av- eraging sequences of subsets in R d or Z d . We consider the behavior of their Fourier-Bohr coefficients and their spect

In this paper, we shall prove that if $G$ is a countably infinite product of second countable amenable locally compact groups $G_i,i\,{=}\,0,1,2,\dots$ and each $G_i$ is a non-trivial compact group for $i>0,$ then the center of the second conjugate a
