The corner element of generalized numerical semigroups
Matheus Bernardini, Wanderson Tenório, Guilherme Tizziotti
In this paper we introduce the concept of corner element of a generalized numerical semigroup, which extends in a sense the idea of conductor of a numerical semigroup to generalize…

Counting numerical semigroups by genus and even gaps via Kunz-coordinate vectors
Matheus Bernardini
We contruct a one-to-one correspondence between a subset of numerical semigroups with genus and even gaps and the integer points of a rational polytope. In particular, we g…
