Interval oscillation criteria for second-order forced delay differential equations with mixed nonlinearities

In this paper, by classical inequality and Riccati transformation, interval oscillation criteria are established for second-order forced delay differential equation with mixed nonlinearities of the form (r(t)Φa(x(t)))+po(t)Φa(x((t))))+nΣi=1 Pi(t)Φβi(x(τi(t)))=e(t),where t≥to,Φ*(u)=│u│*-1u,τk(t) are non-decreasing with τk(t)≤t,limt→∞τk(t)=∞,k=0,1,2,…,and the exponents satisfy βi>a>O are real number,Pi,i=0,1,2,…,n and e might change signs. They generalize and improve some known results. Example is also given to illustrate the importance of our results.
