On the oscillation of the solutions of nonlinear differential equations with deviating argument. (Über die Oszillation der Lösungen nichtlinearer Differentialgleichungen mit abweichendem Argument.) (Russian) Zbl 0306.34091
In this paper sufficient conditions are introduced for the oscillation of all for \(x\to\infty\) prolongable solutions of the equation
\[
[r(t)y']'+f[t,y(h_1(t)\ldots,y(h_k(t)),A(y)]+F[t,y(z_1(t)),\ldots, y(z_d(t)), B(y)]=0.
