Strong Oriented Chromatic Number of Planar Graphs without Short Cycles [PDF]
Discrete Mathematics & Theoretical Computer Science, 2008 Let M be an additive abelian group. An M-strong-oriented coloring of an oriented graph G is a mapping f from V(G) to M such that f(u) j(v) whenever uv is an arc in G and f(v)−f(u) −(f(t)−f(z)) whenever uv and zt are two arcs in G.

A note on graph theory techniques for brain tumor detection [PDF]
Romanian Journal of Neurology, 2022 Brain Tumors are detected in people of all age groups. It leads to various complications that are both physiological and psychological. Graph theory techniques are employed to study both functional and structural behavior of brain networks.

Journal of Graph Algorithms and Applications, 2005 Summary: The task of drawing subgraphs is often underestimated and they are simply emphasized using different colors or line styles. In this paper, we present an approach for drawing graphs within graphs that first produces a layout for the subgraphs thus increasing their locality.

Towards Inferring Influential Facebook Users
Computers, 2021 Because of the complexity of the actors and the relationships between them, social networks are always represented by graphs. This structure makes it possible to analyze the effectiveness of the network for the social actors who are there.
