Hi, Lindy-
The developer of MathCAT responded with this question:
could you check with Lindy about the translation. I don't think she realized that the <code class="notranslate">k</code> and the <code class="notranslate">l</code> are in separate subscripts. Lindy's Nemeth translation places them in the same subscript. That is mathematically wrong because it would imply the last tensor index is "k times l" whereas there are actually four of them and the 'k' and 'l' are not (implied) multiplication. With that correction (and knowing that MathCAT leaves it up the to caller to add the Nemeth switch indicators), <code class="notranslate">⠠⠗⠰⠊⠐⠘⠚⠐⠰⠅⠐⠰⠇</code> as the correct MathCAT generates appears correct.
Does this make sense, Lindy?
Thanks!
Brian
