Rectilinear crossing number of a zero divisor graphKeywords: Zero divisor graph , Crossing number , Rectilinear crossing number Abstract: In this paper, we evaluate the rectilinear crossing number of Γ(Zn).We mainly focus on finding the rectilinear drawing of zero divisor completegraphs especially for p = 7, 11. Finally, we compare the rectilinearcrossing number with the crossing number thereby forming an inequalityby different conjectures.
