C-semigroups with its induced order

Let $C\subset {\mathbb{N}}^p$ be an integer polyhedral cone. An affine semigroup $S\subset C$ is a $C$-semigroup if $\mathrm{\mid }C\setminus S\mathrm{\mid }<+\mathrm{\infty }$. This structure has always been studied using a monomial order. The main issue is that the choice of these orders is arbitrary. In the present work we choose the order given by the semigroup itself, which is a more natural order. This allows us to generalise some of the definitions and results known from numerical semigroup theory to $C$-semigroups.
