Abstract
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 for L(Γ(Zpq), and establish the relation among point covering, independence number and
edge covering number of L(Γ(Zpq), where p and q are prime numbers.
