Resumo: In first-passage percolation the edges of the Z^2 nearest-neighbour lattice are equipped with non-negative random weights. The resulting weighted graph induces a random metric on Z^2. The study of infinite geodesics in first-passage percolation was pioneered by Newman in the 1990s. The aim of this mini-course will be to describe the ergodic theory for infinite geodesics developed in recent work of Ahlberg-Hoffman, based on previous work of Hoffman and Damron-Hanson. This will lead us to discuss concepts such as coalescence, Busemann functions and random coalescing geodesics, which are key ingredients in this development. Lecture 1: Basics on first-passage percolation and geodesics. Lecture 2: Busemann functions and competing growth. Lecture 3: Random coalescing geodesics. Lecture 4: An ergodic theory for infinite geodesics.
