In this paper we obtain conditions on the coefficients of a cubic Lotka–Volterra system of the form _ x 1⁄4 xð2 a20x a11xy a02yÞ; _ y 1⁄4 yð 3þ b20x þ b11xyþ b02yÞ; ð1Þ which fulfillment yields the existence in a neighborhood of the origin of a first integral of the form /ðx; yÞ 1⁄4 x3y2 þ h:o:t:, in which case the origin is termed a 2 : 3 resonant center.(More)
