Let Γ=⟨α,β⟩ be a numerical semigroup. In this article we consider the dual Δ∗ of a Γ-semimodule Δ; in particular we deduce a formula that expresses the minimal set of generators of Δ∗ in terms of the generators of Δ. As applications we compute the minimal graded free resolution of a graded F[tα,tβ]-submodule of F[t], and we investigate the structure of the selfdual Γ-semimodules, leading to a new way of counting them.
