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)
