The primitive ideal space of the partial-isometric crossed product corresponding to an action induced by the multiplication on $p$ -adic integers

Saeid Zahmatkesh

For an odd prime $p$ , we consider an action $α$ of the semigroup $N^{2}$ on the algebra $C (Z_{p})$ induced by the multiplication on the compact topological ring of…
