Invariant operators, orthogonal bases and correlators in general tensor models

We study invariant operators in general tensor models. We show that representation theory provides an efficient framework to count and classify invariants in tensor models of (gauge) symmetry Gd=U(N1)⊗⋯⊗U(Nd). As a continuation and completion of our earlier work, we present two natural ways of count...
