On polyhedral graphs and their complements
1EPFL, MA SB Batiment 8, Lausanne, Switzerland.
Researchers identified polyhedral graphs whose complements are also polyhedral. All such graphs are self-complementary, meaning they are isomorphic to their own graph complements.
Area of Science:
- Graph theory
- Discrete mathematics
- Combinatorics
Background:
- Polyhedral graphs are a key concept in graph theory, relating to the structure of polyhedra.
- Understanding graph complements is crucial for studying graph properties and symmetries.
Purpose of the Study:
- To characterize polyhedral graphs whose complements are also polyhedral.
- To determine the relationship between polyhedral graphs and self-complementary graphs.
Main Methods:
- Graph theoretical analysis
- Characterization of graph properties
- Exploration of graph complements
Main Results:
- Identified the complete set of polyhedral graphs that remain polyhedral under complementation.
- Demonstrated that all such graphs are self-complementary.
Conclusions:
- The property of being polyhedral is preserved under complementation if and only if the graph is self-complementary.
- This finding provides a deeper understanding of the structure and symmetries of polyhedral graphs.

Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
