Conditionally Bi-Free Independence with Amalgamation
Yinzheng Gu, Paul Skoufranis
In this paper, we introduce the notion of conditionally bi-free independence in an amalgamated setting. We define operator-valued conditionally bi-multiplicative pairs of functions…
Conditionally Bi-Free Independence for Pairs of Algebras
Yinzheng Gu, Paul Skoufranis
In this paper, the notion of conditionally bi-free independence for pairs of algebras is introduced. The notion of conditional -cumulants are introduced and it is demons…
Majorization in C*-algebras
Ping Wong Ng, Leonel Robert, Paul Skoufranis
We investigate the closed convex hull of unitary orbits of selfadjoint elements in arbitrary unital C*-algebras. Using a notion of majorization against unbounded traces, a characte…
Closed convex hulls of unitary orbits in certain simple real rank zero C-algebras
Ping Wong Ng, Paul Skoufranis
In this paper, we characterize the closures of convex hulls of unitary orbits of self-adjoint operators in unital, separable, simple C-algebras with non-trivial tracial simplex…
