The search for Invariants for 3D Systems of 1ODEs - a new Method and Integrability Analysis
In [1], we have presented the theoretical background for finding the
Elementary Invariants for a 3D system of first order rational differential
equations (1ODEs). We have also provided an algorithm to find such Invariants.
Here we introduce new theoretical results that will lead to a novel, more
efficient, approach to determine these invariants. Furthermore, one important
aspect of such dynamical systems is that the integrability can be an issue. We
will show that the present theoretical development allows for an Integrability
analysis in the case where the system has free parameters.Comment: 10 page
