Equivalence bimodule between non-commutative tori
The non-commutative torus is realized as the -algebra of sections of a locally trivial -algebra bundle over with fibres isomorphic to for a totally skew multiplier on . D. Poguntke [9] proved that is stably isomorphic to for a simple non-commutative torus and an integer . It is well-known that a stable isomorphism of two separable -algebras is equivalent to the existence of equivalence bimodule between them. We construct an --equivalence bimodule.
