In this paper we provide a description of the Haagerup approximation property in terms of Connes’s theory of correspondences. We show that if N ⊂ M is an amenable inclusion of finite von Neumann algebras and N has the Haagerup approximation property, then M also has the Haagerup approximation property. This answers in the affirmative a question of Sorin… CONTINUE READING
