## Discrete Random Surfaces

In this talk we discuss two models of a discrete random surface. The first is a Markov process, like a simple random walk, under which the surface is grown according to random updates. The second chooses the surface uniformly at random, after pinning its height along a boundary, like a simple random bridge. We will explain how these two models exhibit drastically different behaviors, each of which is universal in its own sense.
