Laguerre and Meixner orthogonal bases in the algebra of symmetric functions

Abstract

Analogs of Laguerre and Meixner orthogonal polynomials in the algebra of symmetric functions are studied. This is a detailed exposition of part of the results announced in arXiv:1009.2037. The work is motivated by a connection with a model of infinite-dimensional Markov dynamics.Comment: Latex, 52p
