Abstract:We utilized Banach contraction principle to consider the existence of positive solutions for differential equation with distributed delay as followddty(t)+∫baP(t,θ)y(t-θ)dθ]+∫dcQ(t,θ)y(t-θ)dθ=0and we obtained sufficient conditions which extended existed solution in relevant reference.
Keywords:distributed delay  neutral differential equation  Positive solution
