Explain End(V)

The statement of the theorem says that A_i is in End(V). That notation should be explained. LachlanA (talk) 01:31, 1 October 2009 (UTC)[reply]

Done! The discussion of abstract vector spaces and endomorphisms is, in my opinion, pointless. I've replaced this by a statement in R^n or C^n. I've kept the discussion of abstract vector spaces and endomorphisms, but I've moved it later. The original page claims that theorem was valid in any vector space. I think it's only for real or complex vector spaces. Can anyone verify this? 129.215.104.124 (talk) 13:12, 2 March 2010 (UTC)[reply]

Relation with Cauchy problem

I'm not familiar with this topic, how does the Cauchy-Kowalevski relate to the Cauchy–Lipschitz? Don't they both address the existance of unique solution for the Cauchy problem? --Marco4math (talk) 00:16, 26 February 2010 (UTC)[reply]

wrong direction?

either I am completely confused or f goes in the wrong direction: $f:W\to V$ should be there instead of $f:V\to W$

Link not correct?

The link to the reference Kowalevski, Sophie seems to be wrong.
