[urgent]String theory and poincare invariance

  1. Oct 26, 2014 #1
    My question concerns poincare invariance (I have left out the accent) in bosonic string theory. As far as I know, action of a 1-d String is described by poincare invariance. So my question is: why poincare invariance? And here comes the more ambarassing question: What is poincare invariance(deriviations are more than welcome)? I am refering to Polchinskis first volume of two ,named "Introduction to bosonic string theory". The page is given below...Thanks for any help!

    Thanks for your valueable input.

    You should first understand special relativity before jumping to ST. See e.g. any book om QFT, like Peskin&Schroeder. Or try Zwiebach.

    I have only studied Universitys QM in depth esle I do mathematics. So is poincare invariance part of special relativity does Zwiebach cover metrics?

    Yes and yes. I think Zwiebach is the book you want :)
