Then we discuss some operations on of Picture Fuzzy Graphs (PFGs), including cartesian product of Picture Fuzzy Graphs (PFGs), composition of Picture Fuzzy Graphs (PFGs), union and join of Picture Fuzzy Graphs (PFGs), direct product of Picture Fuzzy Graphs (PFGs), and lexicographic product of Picture Fuzzy Graphs (PFGs). Finally, we discussed application of Picture Fuzzy social network (PFSN).enDr. Atiq ur Rehmansp19Department of MathematicsMathematicsFuzzy GraphsThesis
