چکیده
We characterize the $C^\star$-algebras for which openness of projections in their second duals is preserved under Murray-von Neumann equivalence. They are precisely extensions annihilator by commutative $C^\star$-algebras. also show that all open.

Equivalence of Projections
Theorem: An AW*-algebra is the ring generated by its projections if and only if it has no abelian summand. Corollary: Every equivalence in an A W*-algebra may be implemented by a partial isometry in the ring generated by the projections of the algebra. The corollary is extended to certain finite Baer »-rings. An early proposition in the theory of von Neumann algebras is that every such algebra ...
متن کاملEquivalence of Projections as Gauge Equivalence on Noncommutative Space
Projections play crucial roles in the ADHM construction on noncommutative R. In this article a framework for the description of equivalence relations between projections is proposed. We treat the equivalence of projections as gauge equivalence on noncommutative space. We find an interesting application of this framework to the study of U(2) instanton on noncommutative R: A zero winding number c...
متن کاملAmenability, Bilipschitz Equivalence, and the Von Neumann Conjecture
1. Introduction and statement of results. The geometry of discrete metric spaces has recently been a very active research area. The motivation comes primarily from two (not completely separate) areas of mathematics. The first is the study of non-compact manifolds equipped with metrics well defined up to uniformly bounded distortion. The equivalence classes of these manifolds arise naturally in ...
متن کاملSchur multiplier projections on the von Neumann-Schatten classes
For 1 ≤ p < ∞ let Cp denote the usual von Neumann-Schatten ideal of compact operators on 2. The standard basis of Cp is a conditional one and so it is of interest to be able to identify the sets of coordinates for which the corresponding projection is bounded. In this paper we survey and extend the known classes of bounded projections of this type. In particular we show that some recent results...
متن کاملProjections from a von Neumann algebra onto a subalgebra
— This paper is mainly devoted to the following question : let M, N be Von Neumann algebras with M C N. If there is a completely bounded projection P : N -^ M, is there automatically a contractive projection P : N -^ M? We give an affirmative answer with the only restriction that M is assumed semi-finite. The main point is the isometric identification of the complex interpolation space (AO, Ai ...
