Conditionally Bi-Free Independence for Pairs of Algebras

Understand

In this paper, the notion of conditionally bi-free independence for pairs of algebras is introduced.

• The notion of conditional $(\ell, r)$-cumulants are introduced and it is demonstrated that conditionally bi-free independence is equivalent to mixed cumulants.
• Furthermore, limit theorems for the additive conditionally bi-free convolution are studied using both combinatorial and analytic techniques.
• In particular, a conditionally bi-free partial $\mathcal{R}$-transform is constructed and a conditionally bi-free analogue of the L\'{e}vy-Hin\v{c}in formula for planar Borel probability measures is derived.
