英文摘要Let S be a complex non-singular projective surface of general type with a genus 2 fibration and X(O-S)>= 5. Let G subset of Aut S be a non-trivial subgroup of automorphisms of S, inducing trivial actions on H-i(S,Q) for all i. Then vertical bar G vertical bar=2, K-S(2)=4(X)(O-S) and q(S)=1. Examples of such surfaces are given.; Mathematics; SCI(E); 0; ARTICLE; 3; 1187-1201; 358
