A famous result in classical enumerative geometry says that there are exactly 27 lines on a cubic surface. Meanwhile, a classifying space classifies principal G-bundles. This talk aims to explore a connection between these seemingly unrelated concepts. We will see how classifying spaces give rise to a theory of equivariant integrals, which in turn provides a novel way of addressing the question: “How many lines are there on a cubic surface?”
