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…
Quadrangular embeddings of complete graphs and the Even Map Color Theorem (with details)
Wenzhong Liu, Serge Lawrencenko, Beifang Chen +5
Hartsfield and Ringel constructed orientable quadrangular embeddings of the complete graph for , and nonorientable ones for and $n\equiv 1 \pmod…
Search algorithms for efficient logistics chains
Serge Lawrencenko, Irina A. Duborkina
Logistics networks arise whenever there is a transfer of material substance or objects (such as checked baggage on international flights) as well as energy, information, or finance…
Homology of polyhedra and quadrangulations of surfaces
Serge Lawrencenko
A new formula is obtained in algebraic topology, in terms of Betti numbers, and a new method, called the spinal method, is suggested and developed for generating quadrangulations o…
Irreducible triangulations of the Möbius band
María-José Chávez, Serge Lawrencenko, Antonio Quintero +1
A complete list of irreducible triangulations is identified on the Möbius band.
