Nov 23, 2015 at 16:28 | comment | added | Michael Seifert | Your expression in the tensor above has a misplaced index somewhere — the index $i$ appears three times. If you correct this, I can probably write up some code that will do some of what you want. | |

Nov 22, 2015 at 18:26 | comment | added | user35780 | Thank you! But no, I am working with stochastic field theory. I am trying to solve tensor structures which appears when you write down field theoretical formulation for navier-stokes equations and try to study its critical dynamics (loop corrections, renormalization, RG) | |
Nov 22, 2015 at 2:18 | comment | added | bbgodfrey | Welcome to Mathematica.SE! I hope you will become a regular contributor. To get started, 1) take the introductory tour now, 2) when you see good questions and answers, vote them up by clicking the gray triangles, because the credibility of the system is based on the reputation gained by users sharing their knowledge, 3) remember to accept the answer, if any, that solves your problem, by clicking the checkmark sign, and 4) give help too, by answering questions in your areas of expertise. | |
Nov 22, 2015 at 1:11 | comment | added | Prastt | I think you are better off implementing your own tensor quantities. I.e. sc /: sc[{a_}, {b_}] sc[t_, {a_}] := sc[t, {b}]; so that for example sc[{i},{j}]sc[p,j] will evaluate to sc[p,i]. Btw these projectors look familiar, are you doing some conformal stuff? | |
