Abstract

. We compute the generating series for the simplest class of bi-free cumulants, beyond the free cumulants, the two-bands bi-free cumulants of a pair of a left and a right variable. We also consider two-faced systems with a commutation condition implying that two-bands moments, that is expectation values of the product of a monomial of left and a monomial of right variables determine the other moments. Examples include hyponormal operators, dual systems in free entropy theory and bi-partite systems. Résumé. Pour une paire de variables, une gauche et une droite, nous calculons la série génératrice des plus simples cumulants bi-libres au-delà des cumulants libres. On considère aussi des systèmes à deux faces, satisfaisant une condition de commutation qui assure que les moments à deux bandes, c’est-à-dire les espérances des produits d’un monôme de variables gauches et d’un monôme de variables droites, déterminent tous les autres moments non-commutatifs. Les opérateurs hyponormaux, les systèmes duaux de la théorie de l’entropie libre, ainsi que les systèmes bipartites, fournissent des exemples.

面对的自由概率II: $2$-变量双自由偏$R$-变换和秩$\le1$交换的系统
. We在线使用发电series for the纪念class of bi-free cumulants、beyond the free cumulants the two-bands bi-free cumulants可变of a pair of a left and right。We also联同two-faced systems with a开关implying that two-bands时光,只要瞧广州改良of the products of a monomial of a left and monomial of right ?变量确定the other时光。实例包括二元hyponormal运营商,free entropy systems in theory and bi-partite systems。摘要。对于一对变量,一个左,一个右,我们计算生成最简单的双自由累积数超过自由累积数的级数。我们还考虑了满足切换条件的双面系统,该条件保证了双波段力矩,即单个左变量和单个右变量的乘积的期望,决定了所有其他非切换力矩。例子包括下正则算子、自由熵理论的对偶系统和二部系统。
