摘要: A conjecture of Bloch predicts that the symplectic automorphisms of a complex smooth projective surface S act trivially on the Albanese kernel of the 0-th Chow group. Here an automorphism of S is called symplectic if it acts trivially on H^0(S, K_S). This has been verified for finite order symplectic automorphisms of K3 surfaces by Voisin and Huybrechts, and for surfaces with Kodaira dimension one and \chi(\mathcal{O}_S) not equal to 1 by Du and Liu. In this talk, I will report some work in progress with Jiabin Du on surfaces with a genus 2 fibration.
