Symmetries on almost symmetric numerical semigroups
Hirokatsu Nari
The notion of almost symmetric numerical semigroup was given by V. Barucci and R. Fröberg. We characterize almost symmetric numerical semigroups by symmetry of pseudo-Frobenius num…

Genus of numerical semigroups generated by three elements
Hirokatsu Nari, Takahiro Numata, Kei-ichi Watanabe
In this paper we study numerical semigroups generated by three elements. We give a characterization of pseudo-symmetric numerical semigroups. Also, we will give a simple algorithm…
