Despite efforts towards gender equality, from an early age, girls practice sport less than boys. Explaining this is paramount to psychology. Stereotypes about gender-appropriate behaviour play a key role in doing physical-sports ...
On some families of subsemigroups of a numerical semigroup
(2020-04-07)
To a given numerical semigroup S we associate a family of subsemigroups {휕nS}, n ∈ ℕ, that permits us to understand some of the structure of S. We characterize this family in case S is a supersymmetric numerical semigroup ...
