On the properties of the fundamental dispersions of the equation
The aim of the paper is to study the structure of oscillatory solutions of a nonlinear third order differential equation .
The aim of this paper is to study the global structure of solutions of three differential inequalities with respect to their zeros. New information for the differential equation of the third order with quasiderivatives is obtained, too.
The aim of this paper is to present sufficient conditions for all bounded solutions of the second order neutral differential equation to be oscillatory and to improve some existing results. The main results are based on the comparison principles.
