The composition series of ideals of the partial-isometric crossed product by the semigroup ${\mathbb{N}}^2$

Saeid Zahmatkesh

Suppose that $\alpha$ is an action of the semigroup ${\mathbb{N}}^2$ on a $C^{\ast }$-algebra $A$ by endomorphisms. Let $A{\times }_{\alpha }^{\text{piso}}{\mathbb{N}}^2$ be the associated partial-is…
