So, I realize the basic theory behind Einstein Summation Convention is that any repeated set of indices implicitly indicates a sum over those indices. However, what if an index is repeated three times?
For example, my mathematics professor posted this problem:
εijkajaj = ?
As you can see, j is repeated thrice. So how do I approach this?
