Angular momentum commutation relations and Einstein summation convention
Dear Diracdeltas, on the Clebsch-Gordan_coefficient page you removed the m-summation in the definition of the commutation relations (on 9:17, 26 June 2011). This is only correct if the Einstein-summation convention is used. Don't you think we should mention this, or otherwise put the summation over m back in the equation? I'm not sure it is worth the effort to introduce the summation convention just for a single equation on that page gerritg (talk) 20:25, 21 September 2011 (UTC).
