Center node: "topological drawings of complete bipartite graphs"
  Abstract: Topological drawings are natural representations of graphs in the plane, where vertices are represented by points, and edges by curves connecting the points. Topological drawings of complete graphs and of complete bipartite graphs have been studied extensively in the context of crossing number problems. We consider a natural class of simple topological drawings of complete bipartite graphs, in which we require that one side of the vertex set bipartition lies on the outer boundary of the drawing. #R##N#We investigate the combinatorics of such drawings. For this purpose, we define combinatorial encodings of the drawings by enumerating the distinct drawings of subgraphs isomorphic to K_{2,2} and K_{3,2}, and investigate the constraints they must satisfy. We prove in particular that for complete bipartite graphs of the form K_{2,n} and K_{3,n}, such an encoding corresponds to a drawing if and only if it obeys certain consistency conditions on triples and quadruples. #R##N#For the case of K_{2,n}, we make use of tools from the theory of pseudoline arrangements. For K_{3,n} we show that drawings of the two induced K_{2,n} can be manipulated to yield a drawing of K_{3,n}. #R##N#In the general case of K_{k,n} with k >= 2, we completely characterize and enumerate drawings in which the order of the edges around each vertex is the same for vertices on the same side of the bipartition. We also investigate straight-line drawings of K_{3,n} and relate the realizability problem to that of stretchability of tropical pseudoline arrangements.
