摘要:
Normal form theory is an important tool for the study of the reduction and bifurcation analysis of nonlinear dynamical systems. This paper is to study the reduction for normal form of a class of non-autonomous nonlinear difference systems. For doing this, we compute the transformed system of a given non-autonomous difference system under a near identity formal transformation. Moreover, a recursive formula is derived for the homogeneous terms of the transformed system, which is a powerful tool for reduction of normal forms of non-autonomous nonlinear difference systems. © 2023 SPIE.
