ON STABILITY OF SOLUTIONS OF CERTAIN FOURTH-ORDER DELAY DIFFERENTIAL EQUATIONS被引量:5
《Applied Mathematics and Mechanics(English Edition)》2006年第8期1141-1148,共8页Cemil Tunc 
By the use of the Liapunov functional approach, a new result is obtained to ascertain the asymptotic stability of zero solution of a certain fourth-order non-linear differential equation with delay. The established re...
