My question might sound pretty dumb but i can't find any information relative to the notation δ used as an operator in the documentation of COMSOL on this page at (3-212) https://doc.comsol.com/6.3/doc/com.comsol.help.sme/sme_ug_theory.06.087.html#4015992 Mathematically how is it defined ? Thanks in advance
