摘要：

In this paper, complex integrability and linearizability of cubic Z(2)-equivariant systems with two 1 :q resonant singular points are investigated, and the necessary and sufficient conditions on complex integrability and linearizability of the systems with two 1: (- q) resonant saddles are obtained for q = 1, 2, 3, 4. Moreover, for general positive integer q, the complex integrability and linearizability conditions are classified, and the sufficiency of the conditions is proved. Further, the linearizability conditions of cubic Z(2)-equivariant systems with two 1:q resonant node points are also classified. (C) 2021 Elsevier Inc. All rights reserved.
