Hello, I think I am fundamentally confused with summation convention. For example, if I have
[itex]
\epsilon_{ijk}x_j\delta_{jk}
[/itex]
Can I sift the levi civita and get
[itex]
\epsilon_{ijj}x_j=0
[/itex]
or sift x and get
[itex]
\epsilon_{ijk}x_k\not=0
[/itex]
Each gives a different answer. What mistake am I making here?
Thank you,
Ian
