Abstract:
We present results on the existence of oscillating solutions of specific form (“quasiperiodic” solutions) for a nonlinear differential equation with power nonlinearity. For oscillating solutions to third-order equations of this type, we obtain an asymptotics of extremums, which is expressed through the asymptotics of extremums of a “quasiperiodic” solution. These results clarify the asymptotic formulas for the modules of extremums of solutions obtained by the author earlier.
Keywords:
oscillating solution, asymptotic behavior, nonlinear equation.
