| ABSTRACT: |
It
is well known that the Ermanno-Bernoulli constants derived from
Laplace-Runge-Lenz vector of dynamical systems are efficiently
used to reduce them to coupled harmonic oscillator(s) and conservation
law in the context of point and nonlocal symmetries of dynamical
systems. In this paper, we show that Quasi-Ermanno-Bernoulli
constants derived from the Hamilton vector of dynamical systems
serve the same purpose. We also note that the symmetry groups
obtained from the reduced systems using the Quasi-Ermanno-Bernoulli
constants are equivalent to that obtained from the formal.
