Abstract

Given any semigroup presentation, we may obtain the diagram group. The purpose of this paper is to determine the graphs Γn(P), (n ∈ N), which are obtained from diagram group for the union of two semigroup presentation of integers with s and t different initial generators. The number of vertices and edges in these graphs will be computed.
