Edge version of topological degree based indices of Boron triangular nanotubes
TLDR
The most important topological indices among all these are topological degree-based indices Topological indices in QSAR/QSP as discussed by the authors, which are the most important indices among them.Abstract:
There are many topological indices which have been discussed so far But the most important topological indices among all these are topological degree-based indices Topological indices in QSAR/QSPread more

I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Old and new geometric polyhedra with few vertices
Serge Lawrencenko,A. Lao +1 more
TL;DR: In this article , it is known that there exist 12 triangulations of the 2-torus with the vertex labeled general octahedral graph 4 O which is isomorphic to the complete four-partite graph 2,2,2.2 K , and it is also known that these triangulation can be realized geometrically with the same 1-skeleton in 3-space.

Serge Lawrencenko,Agustin Lao +1 more
TL;DR: In this paper , the authors show that all the triangulations of the (2-torus) projective plane with the vertex labeled complete graph K_6 are realized geometrically with the same 1-skeleton in 4-space.

Topological index based on the ratios of geometrical and arithmetical means of end-vertex degrees of edges
Damir Vukičević,Boris Furtula +1 more
TL;DR: The geometrical arithmetic index (GA) as discussed by the authors is a topological index based on the end-vertex degrees of edges and its basic features are presented in this paper.
