Abstract:
In addition to the reduction method, we present a novel application of
Jacobi's last multiplier for finding Lie symmetries of ordinary differential
equations algorithmically. These methods and Lie symmetries allow unveiling
the hidden linearity of certain nonlinear equations that are relevant in
physics. We consider the Einstein–Yang–Mills equations and Calogero's
many-body problem in the plane as examples.
Keywords:
Lie group analysis, first integral, Jacobi's last multiplier.
