The distribution of zeros of solutions of neutral advanced differential equations Original Research Article

The distribution of zeros of solutions of the neutral advanced differential equations [x(t)+P(t)x(t+r)]ʹ-Q(t)x(t+σ)=0,t≥to,[x(t)+P(t)x(t+r)]ʹ-Q(t)x(t+σ)=0,t≥to, Turn MathJax on Turn MathJax on , is investigated, where P(t), Q(t) C([t0, ∞), R+), τ, σ R+. The estimate for the distance between adjacent zeros of the oscillatory solution of the above equation is obtained.
