# (18.06.) Unity of Amplitudes

KLT relations and new "collinear" relations between scattering amplitudes

hint to a deep connection between gravity and gauge theory. In string

theory, Mellin correspondence between open strings and supergravity and the

single value projection relating heterotic and type I theories, all valid

to all orders in alpha prime, go far beyond what is implied by known string

dualities.

I will discuss these interconnections and speculate on the possible origin

of such a unity of amplitudes.
