QPSI

[QPSI]. A MAPLE package for the determination of quasi-polynomial symmetries and invariants We present the quasi-polynomial symmetries and invariants (QPSI) 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.
