Abstract
Some new oscillation criteria for nonlinear delay difference equation with damping .2xn+pn.xn+F(n,xn.r,.xn..)=0,n=0,1,2,..., ((.)) are given. Our results partially solve the open problem posed in [Math. Bohemica, 125 (2000), 421. 430]. Also, we will establish some new oscillation criteria for special cases of (.), which improve some of the well.known results in the literature.
