Geodesics in First Passage Percolation

We will discuss recent results about the relationship between the limiting shape in first passage percolation and the structure of the infinite geodesics. We will present a solution to the midpoint problem of Benjamini, Kalai and Schramm. This is joint work with Gerandy Brito and Daniel Ahlberg.
