Global bifurcations and phase portrait of an analytically solvable nonlinear oscillator: Relaxation oscillations and saddle-node collisions

Physical Review A, 1987
A second-order nonlinear differential equation whose general solution can be expressed in terms of elementary functions is studied. Analytical expressions describing both the phase portrait and global bifurcations for all values of the parameters are given. With the advantage of being exactly solvable, this equation models essentially the same physical
