THE SMART TRICK OF LEVIS4D THAT NO ONE IS DISCUSSING

In Einstein notation, the duplication of your i index indicates the sum on i. The former is then denoted εijkεimn = δjmδkn − δjnδkm.These properties are essential for knowledge the actions in the tensor in several coordinate methods.ε i j ε i n = δ j n displaystyle varepsilon _ ij varepsilon ^ in = delta _ j ^ n The Levi-Civita image all
