Bloch's conjecture on surfaces of general type with $p_g=q=0, K^2=3$ and with an involution

Algebraic Geometry 2025-04-14 v1

Abstract

In this short note we prove that an involution on certain examples of surfaces of general type with pg=0=q,K2=3p_g=0=q, K^2=3, acts as identity on the Chow group of zero cycles of the relevant surface. In particular we consider examples of such surfaces when the quotient is bi-rational to an Enriques surface or to a surface of Kodaira dimension one and show that the Bloch conjecture holds for such surfaces.
