Would you please give me a reference? The spectral mapping theorem is as follows: If A is a norman n by n matrix and if P(x) is a polynomial. Then the eigenvalues of p(A) is p(the eigenvalues of A). Of course, there is a general theorem on C-star algebra. I am not terribly sure whether it holds only for the operators on the complex vector spaces. But, it holds for your problem by a direct calculation. |
