Abstract
In this paper, by using t-norms, we define complex fuzzy subgroups and normal complex fuzzy subgroups and investigate some of characteristics of them. Later we introduce and study the intersection and composition of them. Next, we define the concept of normality between two complex fuzzy subgroups under t-norms and obtain some properties of them. Finally, we define the image and the inverse image of them under group homomorphisms.
