“…In the literature there are some papers and books, for example Agarwal et al [2], Grace and Lalli [5], Parhi and Das [10,11], Parhi and Padhi [12], Skerlik [13], and Tiryaki and Yaman [14], which deal with the oscillatory and asymptotic behavior of solutions of functional differential equations. In [1,15], the authors used a generalized Riccati transformation and an integral averaging technique for establishing some sufficient conditions which insure that any solution of equation (1.1) oscillates or converges to zero. The purpose of this note is to improve and unify the results in [1,15] and present some new sufficient conditions which insure that any solution of equation (1.1) oscillates when equation ( * * ) is nonoscillatory, or oscillatory.…”
