Notation question
What is $$(I_n \otimes M + N \otimes I_n)$$ ? Shouldn't it be $$(I_n \otimes L + M \otimes I_n)$$ ? Encyclops 23:46, 18 March 2007 (UTC)
 * Sorry, I fix it immediately. I changed the notations to be consistent with \lambda and \mu while editing and I forgot to update that formula. Fph 08:41, 19 March 2007 (UTC)
