论文摘要
最近在文献中引入了麦克斯韦理论的最大对称非线性扩展，称为modmax。该理论保留了线性理论的电磁二元性和共形不变性。在这篇简短的论文中，我们介绍了Modmax理论的伽利略堂兄，用协变形式主义写成，在伽利略的形式上明确证明是不变的。我们讨论了涉及伽利略电磁不变的理论的构建，并展示了该理论的经典结构如何在伽利略共形代数（GCA）的作用下不变。
A maximally symmetric non-linear extension of Maxwell's theory in four dimensions called ModMax has been recently introduced in the literature. This theory preserves both electromagnetic duality and conformal invariance of the linear theory. In this short paper, we introduce a Galilean cousin of the ModMax theory, written in a covariant formalism, that is explicitly shown to be invariant under Galilean Conformal Symmetries. We discuss the construction of such a theory involving Galilean electromagnetic invariants, and show how the classical structure of the theory is invariant under the action of Galilean Conformal Algebra (GCA).
