On normalized Laplacian spectrum of zero divisor graphs of commutative ring ℤn
For a finite commutative ring ℤ n with identity 1 ≠ 0 , the zero divisor graph Γ (ℤ n ) is a simple connected graph having vertex set as the set of non-zero zero divisors, where two vertices x and y are adjacent if and only if xy=0. We …
