Description
The Emergence Proposal indicates that terms in the low-energy effective action emerge at one-loop from integrating out towers of states becoming exponentially light in asymptotic regions of the moduli space. If correct, it can provide us with a novel tool to investigate quantum gravity from a bottom-up perspective. At present, the precise realization of this general idea in string theory is not completely understood. In this talk, we report progress along this direction. We show that an exact version of the Emergence Proposal is realized in a certain decompactification limit on the moduli space of type IIA string theory on a Calabi-Yau threefold. Since this limit is implemented at strong coupling, our results indicate that emergence can be a property of M-theory. On the other hand, the same exact version seems not to hold for limits in which a weakly coupled heterotic string arises. Extrapolating our strategy to critical type IIA string theory, we speculate on a possible 'perturbative' description of M-theory on a circle.
