Title: Surfaces Are Everywhere

Abstract: We discuss the construction of infinitely many commensurability classes of thin surface subgroups of a cocompact lattice in all (but a few low-dimensional exceptions) simple classical Lie groups G of non-compact type. The construction is geometric and builds on the groundbreaking work of Kahn and Markovic.
