Sheela Suthar & Om Prakash · Journal of Advances in Mathematics and Computer Science · 2014

Let Zn be the commutative ring of residue classes modulo n, Γ(Zn) the zero divisor graph of Zn and L(Γ(Zn) be the line graph of Γ(Zn). We have studied the point covering number and independence number of L(Γ(Zn)), for some positive integer n. We have computed edge covering number...
