Homologically trivial smooth involutions on K3 surfaces. (English) Zbl 0808.57013

In this very nice paper, the author demonstrates, using only the \(G\)- signature theorem and standard branched covering arguments, that if there is an orientation preserving locally linear involution on a closed connected oriented spin 4-manifold \(M\) with \(H_ 1(M; \mathbb{Z}_ 2) = 0\) which operates as the identity on \(H_ 2(M; \mathbb{Q})\), then the signature of \(M\) vanishes.
