Abstract
Let k be an arbitrary field. In this note, we show that if a sequence of relatively prime positive integers a = (a 1, a 2, a 3, a 4) defines a Gorenstein non complete intersection monomial curve \(\mathcal{C}(a)\) in \(\mathbb{A}_k^4\), then there exist two vectors u and v such that \(\mathcal{C}(a + tu)\) and \(\mathcal{C}(a + tv)\) are also Gorenstein non complete intersection affine monomial curves for almost all t ≥ 0.
