| Abstract | The notion of numerical semigroups on ℕxℕ is defined similarly to numerical semigroups on ℕ. We investigate subsets of ℕxℕ which generate numerical semigroups on ℕxℕ. Moreover, we define and investigate irreducible and symmetric numerical semigroups on ℕxℕ. We provide some characterization of irreducible and symmetric numerical semigroups on ℕxℕ. Finally, we study conditions of numerical semigroups on ℕxℕ that can be expressed as an intersection of symmetric numerical semigroups on ℕxℕ. |
