Intersections of Schubert varieties and eigenvalue inequalities in an arbitrary finite factor
H. Bercovici, B. Collins, K. Dykema +2
It is known that the eigenvalues of selfadjoint elements a,b,c with a+b+c=0 in the factor R^omega (ultrapower of the hyperfinite II1 factor) are characterized by a system of inequa…

Characteristic functions for multicontractions and automorphisms of the unit ball
Chafiq Benhida, Dan Timotin
A \emph{multicontraction} on a Hilbert space $\HH$ is an -tuple of operators acting on $\HH$, such that $\sum_{i=1}^n T_i T_i^*\le \1_\HH$. We obtain some resu…
