Abstract
This study provides two theorems defining two classes of conservative nonlinear oscillators that have some characteristics of the linear harmonic oscillators one of which is an amplitudeindependent period These theorems also define their response in terms of initial conditions The first class of these nonlinear oscillators is also characterized by a constant amplitude while the amplitude of the second one decreases in time A few illustrative examples are also presented
