Planar Groups
In abstract algebra courses, teachers are often confronted with the task of drawing subgroup lattices. For purposes of instruction, it is usually desirable that these lattices be planar graphs (with no crossings). We present a characterization of abelian groups with this property. We also resolve the following problem in the abelian case: if the subgroup lattice is required to be drawn hierarch...
متن کاملAutomorphism Groups of Planar Graphs
By Frucht’s Theorem, every abstract finite group is isomorphic to the automorphism group of some graph. In 1975, Babai characterized which of these abstract groups can be realized as automorphism groups of planar graphs. In this paper, we give a more detailed description of these groups in two steps. First, we describe stabilizers of vertices in connected planar graphs as the class of groups cl...
متن کاملPlanar Families of Discrete Groups
Determining the space of free discrete two generator groups of Möbius transformations is an old and difficult problem. In this paper we show how to construct large balls of full dimension in this space. To do this, we begin with a marked discrete group of non-separating disjoint circle type, nsdc group (see section 2.2 for the definition). Such a group determines three disjoint or tangent plane...
متن کاملKazhdan-Lusztig cells in planar hyperbolic Coxeter groups and automata
Let C be a oneor two-sided Kazhdan–Lusztig cell in a Coxeter group (W,S), and let Reduced(C) be the set of reduced expressions of all w ∈ C, regarded as a language over the alphabet S. Casselman has conjectured that Reduced(C) is regular. In this paper we give a conjectural description of the cells when W is the group corresponding to a hyperbolic polygon, and show that our conjectures imply Ca...
