Abstract

We study a Gaussian free field on the hypercube with covariance function related to the transition kernel of a random walk on the hypercube, killed at a geometric random time. An analysis is made of the asymptotic behaviour of the free field as the dimension of the hypercube tends to infinity. We also obtain a result which connects an Ehrenfest urn with geometric killing to a Pólya urn, which is of independent interest.
