 Sep 24 awarded Autobiographer Sep 22 comment Optimizing a rank 3 tensor $F$ is not Hermitian in $u$ and $v$. Sep 22 accepted Optimizing a rank 3 tensor Sep 22 comment Optimizing a rank 3 tensor That's a wonderful answer!!! My paper will see the sun soon, and you will definitely be among the acknowledged people. Thanks a mil... Sep 22 comment Optimizing a rank 3 tensor I agree, but the way I would use to write the program would take days of typing, perhaps there is a concise way of writing down the matrix that you can code here! Sep 22 comment Optimizing a rank 3 tensor @whuber If you mean write all the equations down, like expand for all the indices, then we are talking about 64 equations, which, to me, doesn't sound practical. Sep 21 comment Optimizing a rank 3 tensor @whuber $i$ in the formulas is the imaginary unit. Sep 21 comment Optimizing a rank 3 tensor @whuber Thanks for the comment. I'm just providing 16 entries. Example F_1^i={F_1^1,F_1^2,F_1^3,F_1^4}, which represents the first column in the 4x4 matrix.

I've been running the program since yesterday and still waiting. I think its because my F entries are complicated function of space. Also If, say, we suppress the condition of S being symmetric in the lower indices, would that decrease the time cost? Sep 21 awarded Supporter Sep 20 awarded Student Sep 20 comment Solving antisymmetric tensorial equation Thanks for your answer, Mathematica is running now your code. Hope it works. I logged in with my google account, does it mean I'm registered or I have sign up differently? (sorry for the silly question). Sep 20 revised Solving antisymmetric tensorial equation added 915 characters in body Sep 20 comment Solving antisymmetric tensorial equation @belisarius Thanks for your comments, I have a code that gives me $F$ which is an endomorphisms acting on the tangent space of some moduli space. I will update the questions with what I tried to do...
