### Scattered locally ${C}^{*}$-algebras

#### Abstract

In this article, we introduce the notion of a scattered locally ${C}^{*}$-algebra and we give the conditions for a locally ${C}^{*}$-algebra to be scattered. Given an action $\alpha $ of a locally compact group $G$ on a scattered locally ${C}^{*}$-algebra $A\left[{\tau}_{\Gamma}\right]$, it is natural to ask under what conditions the crossed product $A\left[{\tau}_{\Gamma}\right]{\times}_{\alpha}G$ is also scattered. We obtain some results concerning this question.
