Weighted Galois points for $K3$ surfaces in $\mathbb{P}(1,1,1,3)$

Abstract

This paper introduces a generalization of classical Galois points by extending the ambient space from standard projective spaces to weighted projective spaces. Specifically, the study focuses on smooth weighted hypersurfaces of degree 6 in $\mathbb{P}(1,1,1,3)$ (which are $K3$ surfaces) to determine the defining equations and the number of weighted Galois points. Furthermore, it characterizes these $K3$ surfaces with weighted Galois points in terms of their automorphisms.
