Irreducible triangulations of the once-punctured torus
S. Lawrencenko, T. Sulanke, M. T. Villar +3
A triangulation of a surface with fixed topological type is called irreducible if no edge can be contracted to a vertex while remaining in the category of simplicial complexes and…
Generating families of surface triangulations. The case of punctured surfaces with inner degree at least 4
Maria-Jose Chavez, Antonio Quintero, Maria-Trinidad Villar +1
We present two versions of a method for generating all triangulations of any punctured surface in each of these two families: (1) triangulations with inner vertices of degree at le…
An algorithm that constructs irreducible triangulations of once-punctured surfaces
María José Chávez, Serge Lawrencenko, José Ramón Portillo +1
A triangulation of a surface is irreducible if there is no edge whose contraction produces another triangulation of the surface. In this work we propose an algorithm that construct…
On irreducible triangulations of punctured and pinched surfaces
M. J. Chávez, S. Lawrencenko, A. Quintero +1
A triangulation of a punctured or pinched surface is irreducible if no edge can be shrunk without producing multiple edges or changing the topological type of the surface. The fini…
