Two-dimensional random interlacements and late points for random walks

Abstract : We define the model of two-dimensional random interlacements us-ing the simple random walk trajectories conditioned on never hitting the origin, and then obtain some properties of this model. Also, for the random walk on a large torus conditioned on not hitting the origin up to some time proportional to the mean cover time, we show that the law of the vacant set around the origin is close to that of random interlacements at the corresponding level. Thus, this new model pro-vides a microscopic description of late points of the covering process.
