Abstract
The classification of relevant, marginal and irrelevant operators is studied in the Randall-Sundrum spacetime. We find that there exist marginal and interacting operators in the Randall-Sundrum spacetime unlike a higher-dimensional effective theory near the free-field fixed point. This gives a direction to treat quantum corrections in the field-theoretical framework with extra dimensions by constructing models out of relevant and marginal operators.
