A rational difference equation is a nonlinear difference equation of the form〔Skellam, J.G. (1951). “Random dispersal in theoretical populations”, ''Biometrika'' 38 196−218, eqns (41,42)〕〔(Dynamics of third-order rational difference equations with open problems and Conjectures )〕〔(Dynamics of Second-order rational difference equations with open problems and Conjectures )〕〔Newth, Gerald, "World order from chaotic beginnings", ''Mathematical Gazette'' 88, March 2004, 39-45.〕 : where the initial conditions are such that the denominator never vanishes for any . ==First-order rational difference equation== A first-order rational difference equation is a nonlinear difference equation of the form : When and the initial condition are real numbers, this difference equation is called a Riccati difference equation.〔 Such an equation can be solved by writing as a nonlinear transformation of another variable which itself evolves linearly. Then standard methods can be used to solve the linear difference equation in . 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「Rational difference equation」の詳細全文を読む スポンサード リンク
