Strict comparison and selflessness

Leonel Robert

It is shown that an infinite dimensional, simple, unital, monotracial C*-algebra with strict comparison with respect to its trace is selfless.

Bang--bang representation of embeddable stochastic matrices

Leonel Robert

We prove that every embeddable row-stochastic matrix is a product of at most seven elementary row-stochastic matrices. Frydman's example shows that this bound is sharp.…

Selfless C*-correspondences, operator valued C*-probability spaces and completely positive maps

David Gao, Marius Junge, Srivatsav Kunnawalkam Elayavalli +2

We develop a general theory of selflessness for C*-correspondences, with several applications. Specializing this theory to completely positive maps, in particular to conditional ex…
