The Fractal Diagram of the Dynamical System of the Biquadratic Polynomials
双二次多项式动力系统的分形图

This paper is concerned with the fractal diagram of the Julia of the biquadratic polynomials, which is suggested to A. Douady in the last century. By means of the qualitative of those fractal diagram,we verify the property of the connectedness locus of the single parameter of the biquadratic polynomial and Julia set. We draw the Julia set of the biquadratic polynomial.
