Old and new geometric polyhedra with few vertices
Serge Lawrencenko, Alex Lao
This paper deals with triangulations of the 2-torus with the vertex labeled general octahedral graph which is isomorphic to the complete four-partite graph ; it…

Determination of the 4-genus of a complete graph (with an appendix)
Serge Lawrencenko, Beifang Chen, Hui Yang
In this paper, the quadrangular genus (4-genus) of the complete graph is shown to be for orientable surfaces. This means that $K_p…

On the minimum order of a quadrangulation on a given closed 2-manifold
Serge Lawrencenko
A partial formula is provided to calculate the smallest number of vertices possible in a quadrangulation on the closed orientable 2-manifold of given genus. This extends the previo…
