The Extension of Diagram Group over Semigroup Presentation
Kalthom Mahmood Almabrok · Asian Research Journal of Mathematics · 2023
In this paper, we will discuss the diagram groups from union of two semigroup presentations namely 2S , =< X,Y : X = Y >, 3S = < a,b,c : a = b, b = c,c = a, > and their two complex graphs will be presented. The covering space will be determined by selecting normal su...
