Talk:Polyakov action

I've added some important information about Polyakov action. ES 16/04/2007 00:20 CEST.

Sign convention
I don't mind whether the (+---) or (-+++) convention is used, but wouldn't it be pleasant if it would at least be the same one as in Nambu-Goto action? 15:13, 14 April 2008 (UTC)

Equations of Motion
There's a bit of sleight of hand in your discussion of the equations of motion: the target spacetime metric magically becomes Minkowski! We only get nice free field theories for the bosons X^mu when the target is flat. In general the EOMs are not massless wave equations. Don't mean to be pedantic but up till then the discussion has been nicely general. —Preceding unsigned comment added by 81.105.246.148 (talk) 00:23, 17 April 2009 (UTC)

Some improvements
I clarified a point (Minkowski target space) and added references. But this latter point should be significantly improved as it was not properly managed when this entry was written down.--Pra1998 (talk) 10:55, 14 July 2009 (UTC)

Leonard Susskind - Inventor?
I know that Leonard Susskind made an offhand comment that he "invented" these in his lecture, but I don't know how literally that should be taken. Is there any other evidence (journal papers, books, etc.) that he should be acknowledged in the lead paragraph as the "inventor"?
