Nine research papers from a March 2002 conference shed light on various areas of combinatorics and dynamical systems, with computer algebra as an underlying and unifying theme. Topics covered are irregular connections, rank reduction and summability of solutions of differential systems, asymptotic behavior of divergent series, integrability of Hamiltonian systems, multiple zeta values, quasi polynomial formalism, Padè approximants related to analytic integrability, and hybrid systems. The book will be of interest to mathematicians and theoretical physicists. There is no subject index.
