| Abstract |
We consider the ordinary differential equation of the second order containing in the righthand
side the sum of nonlinearities correctly varying concerning unknown function and its
derivative of the first order. Necessary and sufficient conditions of existence of a wide class of
monotone solutions, and exact asymptotic representations of solutions from the given class in
a neighborhood of a singular point are established. |
