Feynman Graphs from D-Particle Dynamics

It is argued that quantum propagation of D-particles in the limit \alpha'-> 0 can represent the "joining-splitting" processes of Feynman graphs of a certain field theory in the light-cone frame. So basically it provides the possibility to define a field theory by its Feynman graphs. The application of this observation to define M-theory by an energetic expansion approach is discussed.
