Namely, while the bulk terms of perturbation theory are integrals with delocalized propagators, the obstruction terms are integrals with δ-functions, which makes it possible to cancel them with interactions of higher-order. Moreover, the cancellation may fix values of parameters that were free ...
We keep them generic for the moment ( j f 𝑗𝑓 with f a triple identifying a boundary triangle). We regularized the amplitude removing one S L ( 2 , C ) 𝑆𝐿(2,ℂ) integration for each vertex as discussed above. In Equation (12) we indicate the removed integrals with a ...
