The relationship between the peripheral and Poisson boundaries is clarified.
Abstract
The operator space generated by peripheral eigenvectors of a unital normal completely positive map on a von Neumann algebra has a C*-algebra structure. This C*-algebra is known as the \textit{peripheral Poisson boundary} of . For a separable Hilbert space , consider the full fock space defined over . In this paper, we study the peripheral Poisson boundary of the completely positive map, induced by left creation operators of the basis vectors of , on and explore its behavior with respect to the Poisson boundary.
