Hereditary C*-Subalgebra Lattices
Charles A. Akemann, Tristan Bice
We investigate the connections between order and algebra in the hereditary C*-subalgebra lattice and *-annihilator ortholattice . In particul…
Which multiplier algebras are -algebras?
Charles A. Akemann, Massoud Amini, Mohammad B. Asadi
We consider the question of when the multiplier algebra of a -algebra is a -algebra, and show that it holds for a stable -algebra exa…
Weak Paveability and the Kadison-Singer Problem
Charles A. Akemann, Joel Anderson, Betul Tanbay
The Kadison-Singer Problem (K-S) has expanded since 1959 to a very large number of equivalent problems in various fields. In the present paper we will introduce the notion of weak…
The Kadison-Singer problem for the direct sum of matrix algebras
Charles Akemann, Joel Anderson, Betul Tanbay
Let denote the algebra of complex matrices and write for the direct sum of the . So a typical element of has the form \[x = x_1\oplus x_2 \... \oplu…
Conditional expectations onto maximal abelian *-subalgebras
Charles A. Akemann, David Sherman
We determine when there is a unique conditional expectation from a semifinite von Neumann algebra onto a singly-generated maximal abelian *-subalgebra. Our work extends the results…
A Note On The Kadison-Singer Problem
Charles A. Akemann, Betul Tanbay, Ali Ulger
Let H be a separable Hilbert space with a fixed orthonormal basis (e_n), n>=1, and B(H) be the full von Neumann algebra of the bounded linear operators T: H -> H. Identifying l^\in…
