Maximal Product and Symmetric Difference of Complex Fuzzy Graph with Application

A complex fuzzy set (CFS) is described by a complex-valued truth membership function, which combination of standard true function plus phase term. In this paper, we extend the idea graph (FG) to (CFG). The CFS complexity arises from variety values that its can attain. contrast range expanded plane’s unit circle rather than [0,1]. As result, provides mathematical structure for representing in terms numbers. recent times, technique has been popular way combine several features. Using preceding technique, introduce strong approaches are properties CFG. We define order and size discuss degree vertex total describe basic operations, including union, join, complement show new maximal product symmetric difference operations on CFG, along with examples theorems go them. Lastly, at base graph, application would be important measuring symmetry or asymmetry acquaintanceship levels social disease: COVID-19.
