Title: Selected topics in algebraic combinatorics and random walks.
Abstract. Selected problems in algebraic combinatorics and random walks are considered. Orthogonal polynomials and generating functions play here a key role. In particular, we relate combinatorics of the Dyk and Motzkin paths and birth-death processes with the theory of orthogonal polynomials and continued fraction.
