Existence of nonnegative solutions are established for the periodic problem y ' = f ( t , y ) a.eȯn [ 0 , T ] , y ( 0 ) = y ( T ) . Here the nonlinearity f satisfies a Landesman Lazer type condition.

This paper deals with oscillatory and asymptotic behaviour of solutions of second order quasilinear difference equation of the form Δ ( a n - 1 | Δ y n - 1 | α - 1 Δ y n - 1 ) + F ( n , y n ) = G ( n , y n , Δ y n ) , n ∈ N ( n 0 ) ( E ) where α > 0 . Some sufficient conditions for all solutions of (E) to be oscillatory are obtained. Asymptotic behaviour of nonoscillatory solutions of (E) are also considered.
