Abstract

This paper presents some new results on permissible degree sets in polygon visibility graphs (PVGs). If the PVG has \( n \) vertices, we say it is an \( n \)-PVG. We also show some canonical construction techniques for PVGs with given degree sets.

Keywords: Visibility graph, polygon visibility graph, degree sequence, degree set, regular graph. 2000 Mathematics Subject Classification: 050
