Title:
Nonlinear oscillation and Multiscale dynamics in a closed chemical
reaction

Abstract: 
In this work, we propose a reversible Lotka-Volterra system to model a
closed isothermal chemical reaction and study its oscillating behavior
and long term dynamics. This is a three dimensional system consisting
of a classical two dimensional conservative Lotka-Volterra model and
dissipative and singular perturbation. In the phase space, the system
exhibits damped oscillation followed by a transition into
non-oscillating behavior and eventually approaches the
equilibrium. The detailed analysis is provided.
