Necessary and Sufficient Conditions for Oscillations of Functional Differential Equations
Necessary and Sufficient Conditions for Oscillations of Functional Differential Equations
In this survey, necessary and sufficient conditions for the oscillation of solutions of retarded, advanced and neutral differential equations of first and higher order with one or several constant coefficients and constant arguments, in terms of the characteristic equation, are presented.Explicit (in terms of the constant coefficient and constant argument …
