| Title | Shifted numerical semigroups |
| Participants | Laura Iglésias, Ana Margarida Neto (Principal Investigator), Manuel Silva |
| Summary | A shifted numerical semigroup is a set of the form S+t={s+t∣ s∈S}, for some numerical semigroup S and some integer t. With this work we want to characterize those that remain numerical semigroups and to establish formulas for their Frobenius number, the number of generators, and their density. |
