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…
