杜阿迪
Examples
- A . douady had suggested to study dynamics of biquadratic polynomials . by definition , a biquadratic polynomial is the composition of two quadratic polynomials , so it is an even quartic polynomials which can be written as f ( z ) = z4 + az2 + 6 , where a , b are parameters . it is easy to see that / has a critical point at 0 and two symmetric critical points at
A . douadv曾建议对双二次多项式的动力系统进行研究，所谓双二次多项式就是两个二次多项式的复合，也即偶四次多项式，在一个线型共轭下可以记为fz ) = z ~ 4 + z ~ 2 + b ，这里o ， b是参数，点0是它的一个临界点，另外还有两个对称的临界点( ( - a ) 、 2 ) ~ 2 。
