[edit] 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)
