摘要

In this paper, we consider the discrete membrane model in four dimensions. We confirm the existence of the scaling limit of the intermediate (i.e., a multiple of the expected maximum) level-sets of the model, and show that it is equal in law to a tilted version of the sub-critical Gaussian multiplicative chaos (GMC) measure of the continuum membrane model.
