On Two Conjectures Concerning \((a, d)\)-Antimagic Labellings of Antiprisms

A connected graph \(G = (V, E)\) is \((a, d)\)-antimagic if there exist positive integers \(a, d\) and a bijection \(g: E \to \{1, 2, \ldots, |E|\}\) such that the induced mapping
\[f_g = \Sigma\{g(u,v): (u, v) \in E(G)\}\, \text{is injective and}\]
\[f_g(V) = \{a, a+d, a+2d, \ldots, a+(|V|-1)d\}.\]
In this paper, we prove two conjectures of Baca concerning \((a, d)\)-antimagic labelings of antiprisms
