Oscillation of Delay Dynamic Equations with Oscillating Coefficients

In this paper, we study the following delay dynamic equation xΔ(t)+ p(t)x(τ(t)) = 0 for t ∈ [t0,∞)T , where t0 ∈ T , supT = ∞ , p ∈ Crd([t0,∞)T,R) alternates in sign infinitely many times and τ ∈ Crd([t0,∞)T,T) is a strictly increasing unbounded function satisfying τ(t) t for all t ∈ [t0,∞)T . Our results extend recent results for arbitrary time scales. Mathematics subject classification (2010): 39A10, 34C10.
