Linear time recognition of Helly circular-arc models and graphs

open access: yes, 2007
. A circular-arc model (C, A) is a circle C together with a collection A of arcs of C. If A satisfies the Helly Property then (C, A) is a Helly circular-arc model.

Neutrosophic Circular-arc Graphs and Proper circular-arc Graphs

open access: yes
Graph theory is a fundamental branch of mathematics that studies networks made up of nodes (vertices) and connections (edges). A key concept in graph theory is the intersection graph, where vertices represent sets, and edges are drawn between vertices if
