We study exceptional sets of the local time of the continuous-time simple random walk in scaled-up (byN) versionsof bounded open domains. Upon exit from, the walk lands on a “boundary vertex” and then reentersthrough a random boundary edge in the next step. In the parametrization by the local time at the “boundary vertex” we prove that, at times corresponding to a-multiple of the cover time of, the sets of suitably defined-thick (i.e., heavily visited) and-thin (i.e., lightly visited) points are, as, distributed according to the Liouville Quantum Gravitywith parameter-times the critical value. For, also the set of avoided vertices (a.k.a. late points) and the set where the local time is of order unity are distributed according to. The local structure of the exceptional sets is described as well, and is that of a pinned Discrete Gaussian Free Field for the thick and thin points and that of random-interlacement occupation-time field for the avoided points. The results demonstrate universality of the Gaussian Free Field for these extremal problems.
