- Homework Statement
- I know what I need to do but I am stuck on one of the steps
- Relevant Equations
- Levi-civita and Kronecker delta identities
εikl εjmngkmMkn =
εikl εjknMkn = (in book it changed sign to -εikl εjknMkn - Why? )
By identity
εikl εnjkMln = (δinδkj - δijδkn)Mkn = ?
I then get ..
Mji - δij Mnn ( is this correct ?)
There 's more to the question but if can get this part right, I should be able to complete the rest.
