[QPSI] A maple package for the determination of quasi-polynomial symmetries and invariants

Abstract We present the QPSI (Quasi-Polynomial Symmetries and Invariants) MAPLE package for the systematic determination of quasi-polynomial symmetries, invariants and invariant tensor fields for dynamical systems. A brief survey of the theoretical results obtained by the authors used in the package is given. Title of program: QPSI Catalogue Id: ADJX_v1_0 Nature of problem The search of invariant tensors and invariants for dynamical systems. Versions of this program held in the CPC repository in Mendeley Data ADJX_v1_0; QPSI; 10.1016/S0010-4655(98)00186-6 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
