A group-theoretic framework for low-dimensional topology
Sarah Blackwell, Robion Kirby, Michael Klug +2
A correspondence, by way of Heegaard splittings, between closed oriented 3-manifolds and pairs of surjections from a surface group to a free group has been studied by Stallings, Ja…
Concordance of spheres in 4-manifolds with an immersed dual sphere
Michael Klug, Maggie Miller
Let and be two homotopic, oriented 2-spheres embedded in an orientable 4-manifold . After discussing several operations for modifying an immersion of a 3-manifold in…
Kernels of splitting homomorphisms
Michael R. Klug
Lei and Wu have given a description of the second homotopy group of a closed orientable 3-manifold in terms of the kernels of the epimorphisms from the fundamental group of a Heega…
Some properties of -structures on compact surfaces
Michael R. Klug, Luuk Stehouwer
We show that two -structures on a surface differ by a diffeomorphism of the surface if and only if they are cobordant (for comparison, the analogous fact has al…
Building Groups From Restricted Diagrams of Groups
Nic Brody, Michael R. Klug
We consider the problem of realizing a group as the fundamental group of a graph of groups where the vertex groups are restricted to certain classes (for example, coming from a cer…
Counting homomorphisms from surface groups to finite groups
Michael R. Klug
We prove a result that relates the number of homomorphisms from the fundamental group of a compact nonorientable surface to a finite group , where conjugacy classes of the bound…
