Title
27 Lines on a Cubic Surface
Abstract
It was discovered in the 19th century by Cayley and Salmon that every cubic surfac in 3-dimensional projective space contains exactly 27 lines. These form very special configurations, deeply related to the geometry of the root lattice of type E6.
I would like to discuss some of the many geometric properties of the line configuration and why these are still of interest to geometers.
