EXTENSION ALGEBRAS OF CUNTZ ALGEBRA, II
Abstract In this paper, we construct the unique (up to isomorphism) extension algebra, denoted by E ∞ , of the Cuntz algebra 𝒪 ∞ by the C * -algebra of compact operators on a separable infinite-dimensional Hilbert space. We prove that two unital monomorphisms from E ∞ to a unital …
