摘      要：Let C be a positive integer cone and k ∈ C. A C-semigroup S is kpositioned if for every h ∈ C \ S we have that k − h belongs to S. In this work, we focus on this family of semigroups and introduce primary positioned C-semigroups, characterizing a subfamily of them through the perspective of irreducibility. Furthermore, we provide some procedures to compute all such semigroups, describing a family of graphs containing all the primary positioned C-semigroups for a fixed k ∈ *** Codes 20M14, 06F05, 05C05, 11D07 © 2024, CC BY-SA.
