A complex quadratic polynomial is a quadratic polynomial whose coefficients and variable are complex numbers. ==Forms== When the quadratic polynomial has only one variable (univariate), one can distinguish its 4 main forms: * The general form: where * The factored form used for logistic map * which has an indifferent fixed point with multiplier at the origin〔(Michael Yampolsky, Saeed Zakeri : Mating Siegel quadratic polynomials. )〕 * The monic and centered form, The monic and centered form has the following properties: * It is the simplest form of a nonlinear function with one coefficient (parameter), * It is an unicritical polynomial, i.e. it has one critical point, * It is a centered polynomial (the sum of its critical points is zero),〔Bodil Branner: Holomorphic dynamical systems in the complex plane. Mat-Report No 1996-42. Technical University of Denmark〕 * It can be postcritically finite, i.e. If the orbit of the critical point is finite. It is when critical point is periodic or preperiodic.〔(Alfredo Poirier : On Post Critically Finite Polynomials Part One: Critical Portraits )〕 * It is a unimodal function, * It is a rational function, * It is an entire function. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「complex quadratic polynomial」の詳細全文を読む スポンサード リンク
