On the Behavior of Solutions to Second-Order Differential Equation with General Power-Law Nonlinearity

abstract:
The second-order differential equation with general power-law nonlinearity with continuous potential bounded by positive constants is considered. The behavior of solutions to the equation is studied with respect to the values of nonlinearity. The necessary and sufficient conditions for the existence of a finite right-side boundary of the domain or horizontal asymptote are obtained. The distance to the right-side boundary of the domain and the limits of solutions with horizontal asymptotes near their boundaries are estimated. The continuous dependence of the right-side boundary of the domain and horizontal asymptotes on initial data is proved.
