The purpose of the conference is to stimulate research and foster interaction of researchers interested in Riordan arrays and related topics. The general topic of the conference is the theory and application of Riordan arrays. Particular areas of interest include (but are not limited to) the algebraic structure of the Riordan group, Riordan arrays and combinatorial sums, Sheffer sequences, umbral calculus, lattice paths, combinatorics of posets, lattices and words, graph theory, and many other aspects of combinatorics and their relationships with other areas of mathematics, computer science, physics, biology, and other fields. It is our hope that the conference will provide a convenient platform for the exchange of research experiences and ideas from different research areas related to Riordan arrays and the Riordan group.
