Limit Cycle Problem for Quadratic System with some Applications of a Class I
Keywords:
Quadratic system, Limit cycle, Quadratic polynomials
Abstract
This paper is part of a wider study limit cycle problems of a class and planar system; we study the existence of limit cycle for polynomial planar system. In this paper, we present a proof of a result on the existence of limit cycle of the Quadratic System:
