Abstract
The norm closure of the algebra generated by the set {n mapsto { lambda}^{n^k}: lambda in{ mathbb {T}} and k in{ mathbb{N}} } of functions on ({ mathbb {Z}}, +) was studied in cite{S} (and was named as the Weyl algebra). In this paper, by a fruitful result of Namioka, this algebra is generalized for a general semitopological semigroup and, among other things, it is shown that the elements of the involved algebra are distal. In particular, we examine this algebra for ({ mathbb {Z}}, +) and (more generally) for the discrete (additive) group of any countable ring. Finally, our results are treated for a bicyclic semigroup.
