Global first integrals for first order difference equations (original) (raw)

Journal of Difference Equations and Applications, 1998

Abstract

... 1 I Hf(x) =- and Hf(y) =- @(x) NY) Furthermore, since H isa global first integral, this implies H1(x) = H' (y) f' (x). (10) Substituting Eqs. (9) into Eq. (10) gives ... Page 8. 530 LM ARRIOLA Proof Consider the following calculation: Proof' Taking a Taylor scries of Eq. ...
