Abstract
We determine the Weierstrass semigroup \(H(P_{\infty }, P_{1}, \ldots , P_{m})\) at several points on the GK curve. In addition, we present conditions to find pure gaps on the set of gaps \(G(P_{\infty }, P_{1}, \ldots , P_{m})\). Finally, we apply the results to obtain AG codes with good relative parameters.
