Higher Chow cycles on Eisenstein K3 surfaces

Algebraic Geometry 2025-04-15 v1

Abstract

We construct higher Chow cycles of type (2,1) on some families of K3 surfaces with non-symplectic automorphisms of order 3 and prove that our cycles are indecomposable for very general members. The proof is a combination of some degeneration arguments, and explicit computations of the regulator map.
