Sorry, I'm afraid i do not understand, where does that get you? \epsilon_{ikl} \epsilon_{jmn}(\frac{dr_k p_l}{dr_o} \frac{dr_m p_n}{dp_o} - \frac{dr_m p_n}{dr_o} \frac{dr_k p_l}{dp_o}) = \epsilon_{ikl} \epsilon_{jmn}(\delta_{ko}\delta_{no}p_l r_m -\delta_{mo}\delta_{lo} p_n r_k) If that's...

Hi, I am stumped by how to expand/prove the following identity, \{L_i ,L_j\}=\epsilon_{ijk} L_k I am feeling that my knowledge on how to manipulate the Levi-Civita is not up to scratch. Am i correct in assuming, L_i=\epsilon_{ijk} r_j p_k L_j=\epsilon_{jki} r_k p_i Which...
