Projektif Düzlemlerden Elde Edilen Projektif Graflar

Abstract

Bu makalede, uzun bir tarihe ve derin teorilere sahip olan iki alanı, graf teorisi ve projektif geometri arasında bir ilişki kurmak için yeni bir metot sunduk. Bu yeni metodu kullanarak sonlu projektif düzlemlerden elde edilen grafların kombinatoryal özelliklerini araştırdık. Aynı zamanda bu kombinatoryal özellikler ile projektif düzlemin mertebesi arasındaki ilişkileri inceledik.

Projective Graphs Obtained from Projective Planes

Abstract

In this paper, we introduced a new method to relate two areas, graph theory and projective geometry that have a long history and very deep theories. We investigated the combinatorial properties of the graphs which are obtained from finite projective planes by using this new method. Also, we examined the relations between these combinatorial properties and the order of the projective plane.
