A note on the coprime graph of a group [PDF]
In this paper we study the coprime graph of a group $G$. The coprime graph of a group $G$, is a graph whose vertices are elements of $G$ and two distinct vertices $x$ and $y$ are adjacent iff $(|x|,|y|)=1$.

Maximal planar graphs that embed as centers [PDF]
A maximal planar graph is a graph which can be embedded in the plane such that every face of the graph is a triangle. The center of a graph is the subgraph induced by the vertices of minimum eccentricity. We introduce the notion of quasi-eccentric vertices, and use this to characterize maximal planar graphs that are the center of some planar graph.

Algorithmic methods of finite discrete structures. Topological graph drawing (part I) [PDF]
Modern methods of graph theory describe a graph up to isomorphism, which makes it difficult to create mathematical models for visualizing graph drawings on a plane. The topological drawing of the planar part of a graph allows representing the planarization process by algebraic methods, without making any geometric constructions on the plane ...
