Abstract:

String monodromy relations are linear relations among open

string tree amplitudes. They are intrinsically stringy in nature and

it is therefore surprising that we can show them to arise from

low-energy considerations in field theory. In the talk, I will

introduce scattering amplitudes and their properties, explain

low-energy effective field theory, show how string monodromy comes

from contour deformations of the string integrals, and finally present

the argument of how locality, unitary, and linear field theory

amplitude relations allow us to "bootstrap" the string monodromy

relations in the low-energy expansion.
