A note on "Periodic solutions of the Liénard equation with deviating arguments

研究一类具偏差变元的中立型Li啨nard型方程的周期解存在性,给出了这类方程周期解存在性的若干充分条件.

In this paper, a class of neutral type delay Liénard equation is considered. Some suffecient conditions for the existence of periodic solutions for the neutral type delay Liénard equation are obtained.
