Description
Configurations of points and lines have Levi graphs that are well understood. These graphs are bipartite, semi-regular and have girth at least six. They reflect the property that the dual of a configuration of points and lines is again a configuration of points and lines. In case of configurations of points and circles the situation is quite different. For instance, the duality does not preserve the configuration type. In this talk we will explore some questions about the properties of Levi graphs of configurations of points and circles.
