Hamiltonian cycles in (2,3,c)-circulant digraphs
Dave Witte Morris, Joy Morris, Kerri Webb
Let D be the circulant digraph with n vertices and connection set {2,3,c}. (Assume D is loopless and has outdegree 3.) Work of S.C.Locke and D.Witte implies that if n is a multiple…

Amenable groups that act on the line
Dave Witte Morris
Let Gamma be a finitely generated, amenable group. Using an idea of E Ghys, we prove that if Gamma has a nontrivial, orientation-preserving action on the real line, then Gamma has…

Bounded generation and lattices that cannot act on the line
Lucy Lifschitz, Dave Witte Morris
Let D be an irreducible lattice in a connected, semisimple Lie group G with finite center. Assume that the real rank of G is at least two, that G/D is not compact, and that G has m…
