I've been staring at this confused for a while now, and I've just realized that this might be a type-o. Should I assume that the Levi-Civita symbol is only defined on j,k, and that the i is a type-o, or is there an unwritten rule with this notation that gives the i a meaning?
[itex]\sum[/itex]_{j}[itex]\sum[/itex]_{k} ε_{i,j,k} ∂_{j,k}
