            Abstract : 
The concept of (A,B) invariance in linear systems theory generalizes to two concepts for nonlinear systems, (f,g) invariance and local (f,g) invariance. The former implies the latter and the latter implies the former only locally. The topological obstruction to global (f,g) invariance are discussed.
