A ribbon graph derivation of the algebra of functional renormalization for random multi-matrices with multi-trace interactions
{{output}}
We focus on functional renormalization for ensembles of several (say n ≥ 1 ) random matrices, whose potentials include multi-traces, to wit, the probability measure contains factors of the form exp [ - Tr ( V 1 ) × ⋯ × Tr ( V k ) ] for ... ...
