On the Latest Cersion of DESIR-II

Abstract We give a description of the latest version of the DESIR-II package (Barkaton and Jung, 1997; Pflugel, 1996a, b) implemented in Maple V. The purpose of this package is the computation of a fundamental set of formal solutions of n th-order linear differential equations, first-order linear differential systems and asymptotic representations of solutions of n th-order linear difference equations. Our package provides a detailed online-help and a set of additional tools for handling the computed results.
