چکیده انگلیسی
By using averaging functions, new interval oscillation criteria are established for the second-order functional differential equation,(r(t)|xâ²(t)|αâ1xâ²(t))â²+F(t,x(t),x(Ï(t)),xâ²(t),xâ²(Ï(t)))=0,tâ¥t0that are different from most known ones in the sense that they are based on information only on a sequence of subintervals of [t0, â], rather than on the whole half-line. Our results can be applied to three cases: ordinary, delay, and advance differential equations. In the case of half-linear functional differential equations, our criteria implies that the Ï(t) ⤠t delay and Gt(t) ⥠t advance cases do not affect the oscillation. In particular, several examples are given to illustrate the importance of our results.
