- Homework Statement
- Prove εijk εijl = 2δkl
- Relevant Equations
- εijk εilm = δjl δkm - δjm δkl
I assumed that this would be a straightforward proof, as I could just make the substitution l=j and m=l, but upon doing this, I end up with:
δjj δkl - δjl δkj
= δkl - δlk
Clearly I did not take the right approach in this proof and have no clue as to how to proceed.
δjj δkl - δjl δkj
= δkl - δlk
Clearly I did not take the right approach in this proof and have no clue as to how to proceed.
