Inverse eigenvalues theorem

(Find sources: Google (books · news · scholar · free images · WP refs) · FENS · JSTOR · TWL)

I work in linear algebra and I have never seen this basic fact called a "theorem" and given a proper name. A Google search seems to report no results as well, apart from Wikipedia and all the sites copying its content. Fph 21:36, 8 March 2011 (UTC)[reply]

Fixed nomination, which should be close seven days after 02:24, 12 March 2011 (UTC) -- Uzma Gamal (talk) 02:24, 12 March 2011 (UTC)[reply]

Either Merge to Theorems and definitions in linear algebra#Diagonalization, where this theorem isn't given but probably should be, or Redirect to Eigendecomposition of a matrix#Useful facts regarding eigenvalues, where this theorem is already given. Which is more suitable depends in part on which of these two versions of the theorem the rigorous qualified WPMATHematicians consider to be better. Qwfp (talk) 09:05, 15 March 2011 (UTC)[reply]
Redirect to eigendecomposition of a matrix. We don't need a detailed proof of this result. It's a standard exercise in linear algebra courses. Sławomir Biały (talk) 16:16, 15 March 2011 (UTC)[reply]
Redirect I agree with Sławomir Biały. Dingo1729 (talk) 16:55, 15 March 2011 (UTC)[reply]
Redirect as per Sławomir Biały. I've not come across it before, or have long ago forgotten it, but the proof is obvious and trivial.--JohnBlackburne^words_deeds 02:45, 19 March 2011 (UTC)[reply]
Redirect or delete appropriately as discussed above. cannot have a page for this stuff alone0ukieu (talk) 01:11, 20 March 2011 (UTC)[reply]
