Quantum field theory and string theory

What is the relationship between quantum field theory and string theory?

mathman · Sep 26, 2011

If string theory is proven correct, then quantum field theory should be deduced from it where quantum theory holds.

negru · Sep 26, 2011

quantum field theory is always a limit of string theory*. for example, you can deduce things like scattering amplitudes of gluons and gravitons from string theory.

*probably too strong of a statement, it might be possible for some qft's to not be generalizable to string theory (in a non trivial way at least)
