Determining Liouvillian first integrals for dynamical systems in the plane and an integrability analysis
Description
Abstract Here we deal with a semi-algorithm to find Liouvillian first integrals of dynamical systems in the plane. The algorithm is based on a Darboux-type procedure to find the integrating factor for the system. The particular form of such systems allows reducing them to a single rational first order ordinary differential equation (rational 1ODE). Therefore, we have produced some methods and implemented a set of software routines in Maple for dealing with rational 1ODEs. We have also introduced (base... Title of program: Lsolver Catalogue Id: ADZF_v2_0 Nature of problem We deal with the analytical solving of 1ODEs via a Darboux method. We also introduce an integrability analysis for this present case (1ODEs) that was previously presented in the context of 2ODEs.
