AB Let C ⊂ Qp be a rational cone. An affine semigroup S ⊂ C is aC-semigroup whenever (C \ S) ∩ Np has only a finite number of elements.In this work, we study the tree of C-semigroups, give a method togenerate it and study their subsemigroups with minimal embedding dimension. We extend Wilf’s conjecture for numerical semigroups to C-semigroups and give some families of C-semigroups fulfilling the extendedconjecture. We also check that other conjectures on numerical semigroupsseem to be also satisfied by C-semigroups.
