Correspondence between Feynman diagrams and operators in quantum field theory that emerges from tensor model
Abstract A novel functorial relationship in perturbative quantum field theory is pointed out that associates Feynman diagrams (FD) having no external line in one theory $$\mathbf{Th}_1$$ Th1 with singlet operators in another one $$\mathbf{Th}_2$$ Th2 having an additional $$U(\mathcal{N})$$ U(N) symm...
