Oscillation of Second Order Nonlinear Delay Damped Difference Equations.

Some new oscillation criteria for nonlinear delay difference equation with damping 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. [ABSTRACT FROM AUTHOR]
