3-manifold polynomials
José Frías, José Carlos Gómez-Larrañaga, José Luis León-Medina +1
We propose a way to derive polynomial invariants of closed, orientable -manifolds from Heegaard diagrams via cellularly embedded graphs. Given a Heegaard diagram of an irreducib…
Decompositions of three-dimensional Alexandrov spaces
Luis Atzin Franco Reyna, Fernando Galaz-García, José Carlos Gómez-Larrañaga +2
We extend basic results in -manifold topology to general three-dimensional Alexandrov spaces (or Alexandrov -spaces for short), providing a unified framework for manifold and…
The number of Simply-connected Trivalent -dimensional Stratifolds
J. C. Gómez-Larrañaga, F. González-Acuña, Wolfgang Heil
We describe a method for counting the number of -connected trivalent -stratifolds with a given number of singular curves and -manifold components.
2-stratifold spines of closed 3-manifolds
J. C. Gómez-Larrañaga, F. González-Acuña, Wolfgang Heil
-stratifolds are a generalization of -manifolds in that there are disjoint simple closed branch curves. We obtain a list of all closed -manifolds that have a -stratifol…
