Hello, Does anyone know what "induced gravity" is and where can one read (something not too technical) about it? I am trying to understand how a system with zero Lagrangian has something to do with gravity. Could someone explain perhaps? Thanks
The text I read was brief... it only mentioned "zero Lagrangian (i.e. induced gravity)". I would have imagined this meant a system where T and V are equal. I am unsure what would be special in a such zero-lagrangian system. Then the action is zero too. One can't write the euler -lagrange equations either , because all terms are zero or am I missing something?
