Non-commutative perspectives
Edward Effros, Frank Hansen
We prove that the non-commutative perspective of an operator convex function is the unique extension of the corresponding commutative perspective that preserves homogeneity and con…
A Matrix Convexity Approach to Some Celebrated Quantum Inequalities
Edward G. Effros
Some of the important inequalities associated with quantum entropy are immediate algebraic consequences of the Hansen-Pedersen-Jensen inequality. A general argument is given using…
New Perspectives and some Celebrated Quantum Inequalities
Edward G. Effros
Some of the important inequalities associated with quantum entropy are immediate algebraic consequences of the Hansen-Pedersen-Jensen inequality. A general argument is given in ter…
Classifying the Unclassifiables
Edward G. Effros
In 1955 George Mackey suggested that there is a fundamental dichotomy in the unitary representation theory of locally compact second countable groups. He felt that there cannnot be…
Zimmermann Type Cancellation in the Free Faa di Bruno Algebra
Michael Anshelevich, Edward G. Effros, Mihai Popa
The N-variable Hopf algebra introduced by Brouder, Fabretti, and Krattenaler (BFK) in the context of non-commutative Lagrange inversion can be identified with the inverse of the in…
Matrix Revolutions, The Origin of Quantum Variables
Edward G. Effros
An informal guide to the history of Heisenberg's matrix mechanics. It is designed for mathematicians with only a minimal background in either physics or geometry, and it is based u…
