We consider certain class of second order nonlinear nonautonomous delay differential equations of the form a(t)x^{\prime\prime} + b(t)g(x,x^\prime) + c(t)h(x(t-r))m(x^\prime) = p(t,x,x^\prime) and (a(t)x^\prime)^\prime+ b(t)g(x,x^\prime) + c(t)h(x(t-

This paper concerns the fourth order differential equation $$ x''''+ax'''+f(x'')+g(x')+h(x)=p(t). $$ Using the Cauchy formula for the particular solution of non-homogeneous linear differential equations with constant coefficients, we prove that the s

In this paper, we study the uniform boundedness and uniform ultimate boundedness of solutions of the third-order delay differential equation (*) ::: x +φ(x, ˙ x)¨ x + g( ˙ x(t r(t))) + f (x(t r(t))) = p(t, x, ˙ x, ¨), where 0 r(t) γ, γ is a p
