Honeycomb structures, Dirac points and Edge States

``Edge states" are a type of energy-localization along a line-defect, an interface between two different media. Topologically protected edge states are a class of edge states which are stable to strong local distortions of the edge. We present recent results on such states in continuous honeycomb structures. This is joint work with C.L. Fefferman and J.P. Lee-Thorp.
