Abstract:In this paper, we compute certain invariants of extension algebras of the torus algebra $$C({mathbb{T}}^{2})$$ by $${mathcal{K}}$$, where $${mathcal{K}}$$ is the C*-algebra of compact operators on an infinite dimensional separable Hilbert space H. These extension algebras are also constructed up to isomorphism. Received: 5 July 2007, Revised: 14 February 2008
