Hi there,
I 've recently looked at how the Nambu-Goto action of an open string can be derived from the proper area of the parameterised world-sheet, in the form of either the derivatives of space-time coordinates or the determinant of the induced metric.
However, may I ask what are the main advantages and disadvantages of adopting the Polyakov approach instead? Which one of these have a better application on other aspects of string theory?
Cheers!
