Nonoscillatory Solutions of x(m) = (-1)mQ(t)x
A continuous real vector function is said to be nonoscillatory on an interval if at least one of its components is of constant positive or negative sign there. In this note, various existence criteria for nonoscillatory solutions of the system x(m) = (-l)

On Nonoscillation of Advanced Differential Equations with Several Terms
Existence of positive solutions for advanced equations with several terms x˙(t)+∑k=1mak(t)x(hk(t))=0, hk(t)≥t is investigated in the following three cases: (a) all coefficients ak are positive; (b) all coefficients ak are negative; (c) there is an equal

On the oscillation of the solutions to linear difference equations with variable delay
A new criterion for the oscillation of the solutions to linear difference equations with variable delay is established. This criterion is based on a new fundamental lemma, which provides a useful inequality for the nonoscillatory solutions of the ...

On third-order linear difference equations involving quasi-differences
We study the third-order linear difference equation with quasi-differences and its adjoint equation. The main results of the paper describe relationships between the oscillatory and nonoscillatory solutions of both equations.

On oscillatory and nonoscillatory behaviour of solutions of Volterra integral equations
Sufficient conditions are given so that bounded and unbounded solutions of the Volterra integral equation x(t) = ƒ(t) − ∝0t a(t, s) g(s, x(s)) ds are oscillatory or nonoscillatory.
