How do I achieve something like

in LaTeX? The curved lines indicate symmetrization with respect to the indices they join, and the straight lines indicate antisymmetrization.

          Here is a simpleminded proposal.

begin{tikzpicture}[overlay,remember picture]
          
draw[blue,thick] (i1.north east) to[out=30,in=150] (l1.north west);

          • Can you perhaps edit your answer to include the symmetrization below and antisymmetrization above as well? I couldn't get them to work in spite of using something like "draw[red,thick] (j1.south west) to [out=300,in=225] (k1.south west);"

            @leastaction I added a proposal. If you want things to be like in the last example, one may actually use Wick contractions for that, i.e. one may modify the package commands to give you that as well.

            • Can you perhaps edit your answer to include the symmetrization below and antisymmetrization above as well? I couldn't get them to work in spite of using something like "draw[red,thick] (j1.south west) to [out=300,in=225] (k1.south west);"

              @leastaction I added a proposal. If you want things to be like in the last example, one may actually use Wick contractions for that, i.e. one may modify the package commands to give you that as well.
