We find that the quantum loop effects of interactions in the bulk produce infinite contributions that require renormalization by fourdimensional couplings on the orbifold fixed planes. Thus bulk couplings give rise to renormalization group running of brane couplings.en-USJournal Article2016-09-0910.1016/S0370-2693(01)00408-7
