dc.description.abstract	Abstract We study the existence and number of limit cycles for two classes of fourthorder di¤erential equations using …rst-order averaging theory. The …rst class studied is non-autonomous of the form .... x + (1 + p2)•x + p2x = "F (t; x; _x; •x; ... x) where p is a rational number, " is a small real parameter and F is a function of class C2and T-periodic in t. The second class is autonomous of the form .... x + (1 + p2)•x + p2x = "F (x; _x; •x; ... x) where p is a rational number, " is a small real parameter and F is a function of class C2.	en_US
