A Pedagogical Introduction To Critical Percolation Via The Hierarchical Lattice

Abstract

I will give an introduction to critical exponents in Bernoulli percolation by analyzing the model on the hierarchical lattice, a toy model that has much more symmetry than the Euclidean lattice and permits exact computation of several interesting quantities. Along the way I will review some classical topics such as the sharpness of the phase transition.
