Talk:Minimal polynomial

From Wikipedia, the free encyclopedia

The description "The multiplicity of a root λ of p(x) is the geometric multiplicity of λ" is wrong.

For example, take the same example in the desription: Consider the matrix 4In, which has characteristic polynomial (x − 4)n. However, the minimal polynomial is x − 4, since 4I − 4I = 0 as desired. Multiplicity of 4 in the minimum polynomial p(x) is 1, which is different from the geometric multiplicity which we know is 4.

Indeed, but you could have fixed this yourself :-) This is a wiki, after all. Do you agree with my version? Kusma (討論) 19:50, 12 February 2006 (UTC)

...which I had to rewrite again because I had not been thinking. It should be correct now. Kusma (討論) 19:54, 12 February 2006 (UTC)
