Title: Spheres deform to graphs
 
Abstract: The graphs in the title are directed graphs, to which one can associate a C*-algebra by viewing each vertex as a Hilbert space, and each edge as a partial isometry. The spheres in the title are just ordinary spheres. I shall explain how the C*-algebra of continuous functions on a sphere can be "deformed" into a graph C*-algebra. This is a theorem of Hong and Szymanski.
