摘要
We investigate the monic complex-coefficient polynomial of degree n, f(z) := z(n) a(n-1)z(n-1) ... a(0) in the complex variable z and obtain a new annular bound for the zeros of f(z), which is sharper than the previous results and has clear advantages in judging the Schur stability of difference equations. In addition, examples are given to illustrate the theoretical result.
