3. Let T be a linear operator on the finite – dimensional vector space V over the field F. Suppose that
the minimal polynomial for T decomposes over F into a product of linear polynomials. Then there is a
diagonalizable operator D on V and a nilpotent operator N on V such that
(1) T
(ii) DN
D + N,
ND.
The diagonalizable operator D and the nilpotent operator N are uniquely determined by (i) and (ii)
and each of them is a polynomial in T.
