Infinitesimal non-crossing cumulants and free probability of type B
Maxime Fevrier, Alexandru Nica
Free probabilistic considerations of type B first appeared in a paper by Biane, Goodman and Nica in 2003. Recently, connections between type B and infinitesimal free probability we…

Dilating covariant representations of the non-commutative disc algebras
K. R. Davidson, E. G. Katsoulis
Let be an isometric automorphism of the non-commutative disc algebra $\fA_n$ for . We show that every contractive covariant representation of $(\fA_n, ϕ)$ dilates to…
