    • The n-zero-divisor graph of a commutative semigroup 

      Anderson, David F.; Badawi, Ayman (Taylor and Francis, 2022-04-16)
      Let S be a (multiplicative) commutative semigroup with 0, Z(S) the set of zero-divisors of S, and n a positive integer. The zero-divisor graph of S is the (simple) graph Γ(S) with vertices Z(S) ∗ = Z(S) \ {0}, and distinct ...
