The D-colored version of tensor models has been shown to admit a large Nlimit
expansion. The leading contributions result from so-called melonic
graphs which are dual to the D-sphere. This is a note about the Schwinger–
Dyson equations of the tensorial 5
φ4-model (with propagator 1 p2) and their
melonic approximation. We derive the master equations for two- and fourpoint
correlation functions and discuss their solution. |
