We continue the study of AdS loop amplitudes in the spectral representationand in position space. We compute the finite coupling 4-point function inposition space for the large-$N$ conformal Gross Neveu model on $AdS_3$. Theresummation of loop bubble diagrams gives a result proportional to a tree-levelcontact diagram. We show that certain families of fermionic Witten diagrams canbe easily computed from their companion scalar diagrams. Thus, many of theresults and identities of [1] are extended to the case of external fermions. Wederive a spectral representation for ladder diagrams in AdS. Finally, wecompute various bulk 2-point correlators, extending the results of [1].
