Abstract: In this paper, we apply the coningacy and boundedness of the zeros for a polynomial fn(z) with real coefficienta (i=0,1,2,…,n). A new simple geometric criterion for stability of fn(z) is given which is very convenient for application.

Key words: nonlinear dynamic system, normal form, complex inner product averaging method
