Components in graphs of diagram groups over the union of two semigroup presentations of integers(Kumpulan-kumpulan gambar rajah atas kesatuan dua persembahan semikumpulan bagi integer)
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...

| Summary: | 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. |
