Numerical semigroups with concentration two

José C. Rosales, M. B. Branco, Márcio A. Traesel

We define the concentration of a numerical semigroup $S$ as $C (S) = max {next_{S} (s) - s ∣ s \in S \ {0}}$ wherein $\text{next}_S(s)=\min\left\{…

Almost symmetric numerical semigroups with given Frobenius number and type

M. B. Branco, I. Ojeda, J. C. Rosales

We give two algorithmic procedures to compute the whole set of almost symmetric numerical semigroups with fixed Frobenius number and type, and the whole set of almost symmetric num…
