Inverse Integrating Factor Method of Planar Autonomous Polynomial Di erential Systems رسالة ماجستير

Abstract

This thesis is a survey study in which the inverse integrating factor for planar autonomous polynomial di erential systems has been done and some illustrative examples are presented. Also, a quick survey on the relationship between the inverse integrating factor and limit cycle is handled. Furthermore, some aspects of integrability problem, invariant algebraic curves and their relations with inverse integrating factor for planar di erential systems are reviewed.
