Using differential characteristic set method to accurately solve a class of nonlinear rational difference equations
The differential characteristic set method has been used to solve a set of rational difference equations,namely a class of non-linear difference equations.The theoretical knowledge of difference equations and characteristic set methods is introduced firstly.Then,the difference characteristic set method is applied to simplify a class of nonlinear difference equation systems.Through steps such as effectiveness,consistency judgment and reducible decomposition,the zero point set based on the whole order theorem and zero decomposition theorem is finally obtained.
