Trees of Homotopy Types of Two-Dimensional CW-Complexes
Triangulations of 3-dimensional pseudomanifolds with an application to state-sum invariants.
Triangulations of integral polytopes and Ehrhart polynomials.
Twisted Alexander polynomials and surjectivity of a group homomorphism.
Two-fold branched coverings of S3 have type six.
In this work, we prove that every closed, orientable 3-manifold M3 which is a two-fold covering of S3 branched over a link, has type six.
Two-knot groups with torsion free abelian normal subgroups of rank two.
