| Abstract: |
| This paper,using pseudo-division algorithm,introduces a method for computing singular point values of a class of complex polynomial differential systems,establishes the necessary and sufficient conditions for integrability of two classes of complex polynomial differential systems,and verifies all these conditions by constructing integrating factors or formal first integrals. |
| Key words: polynomial differential systems integrability integrating factor singular point quantities |
