Abstract: This paper disucsses oscillations of pre-kind function differentinal equation with cotion,and obtains sharp conditions of equation x′(t)=∑〖DD(〗n〖〗i=1〖DD)〗pi(t)x(t+τi)(t≥t0).The effectiveness is proved by examples.

Key words: cotions, pre-kind, function differential equation, oscillation
