Multivariable Schur-Horn theorems
Pedro Massey, Mohan Ravichandran
We prove a variety of results describing the possible diagonals of tuples of commuting hermitian operators in type factors. These results are generalisations of the classica…
Schur-Horn theorems in II-factors
Martin Argerami, Pedro Massey
We describe majorization between selfadjoint operators in a -finite II factor in terms of simple spectral relations. For a diffuse abelian von Neumann…
Injective envelopes and local multiplier algebras of some spatial continuous trace C*-algebras, II
Martin Argerami, Douglas Farenick, Pedro Massey
We determine the injective envelope and local multiplier algebra of a continuous trace C*-algebra that arises from a continuous Hilbert bundle over an arbitrary locally compact Hau…
Injective Envelopes and Local Multiplier Algebras of Some Spatial Continuous Trace C*-Algebras
Martin Argerami, Douglas Farenick, Pedro Massey
A precise description of the injective envelope of a spatial continuous trace C*-algebra A over a Stonean space Delta is given. The description is based on the notion of a weakly c…
Towards the Carpenter's Theorem
Martin Argerami, Pedro Massey
Let M be a II_1 factor, A a masa in M and E the unique conditional expectation on A. Under some technical assumptions on the inclusion of A in M, which hold true for any semiregula…
Non-commutative Schur-Horn theorems and extended majorization for hermitian matrices
Pedro Massey
Let $\mathcal A\subseteq \mat$ be a unital -subalgebra of the algebra $\mat$ of all complex matrices and let be an hermitian matrix. Let $\U_n(B)$ denote the uni…
The local form of doubly stochastic maps and joint majorization in II factors
Martin Argerami, Pedro Massey
We find a description of the restriction of doubly stochastic maps to separable abelian -subalgebras of a II factor $\cM$. We use this local form of doubly stochastic maps…
A Schur-Horn type theorem for II factors
M. Argerami, P. Massey
Given a II factor M and a masa A of M, we prove a version of the Schur-Horn Theorem, together with a contractive version. These results are inspired on a recent conjecture of A…
