Abstract:

In this paper oscillation of the first order nonhomogeneous neutral differential difference equations
(d)/dt[x(t)+cx(t-τ)]+P(t)x(t-σ)+f(t)=0,tt0 is discussed. The author gets some sufficient conditions for the equations to oscillate and gener-alizes the result of oscillation of some homogeneous equations.

Key words: Neutral type, differential difference equation, nonhomogeneous equation, oscillation solution
