Diffraction of electromagnetic waves by an aperture in an infinite opaque screen is approached using an integral expression characterized by the spatial Fourier transform at the aperture. The group velocity of the field propagated from the aperture assumes a continuous distribution of values corresp
Given a finite simplicial graph G, and an assignment of groups to the vertices of if, the graph product is the free product of the vertex groups modulo relations implying that adjacent vertex groups commute. We use Gromov's link criteria for cubical complexes and techniques of Davis and Moussang to
