In matrix language, that is [itex]T^T=T^{-1}[/itex]. In other words, you are asking if the transpose of [itex]T[/itex] equals the inverse of [itex]T[/itex].yukcream said:I am not sure wheather
matrix T^v_u = {T^u_v}^-1
Is there a typo here? Because here you just seem to be asking if [itex]T^{\mu}_{\nu}[/itex] equals itself, unless there is something else implied by the { } braces.or T^v_u = {T^v_u} is true?
Your notation is a lot like LaTeX, which is what I used to make my math symbols. So, I'm not really that smart. :tongue2:yukcream said:It is great that you can understand my notation~ you are so smart!!
OK, so now you're asking if [itex]T[/itex] is equal to its own inverse. Again, try to write down the matrix and see if that is so.It is my fault that I want to ask is T^v_u = {T^v_u} -1?
