Permutations, isotropy and smooth cyclic group actions on definite 4-manifolds

Abstract

We use the equivariant Yang-Mills moduli space to investigate the relation between the singular set, isotropy representations at fixed points, and permutation modules realized by the induced action on homology for smooth group actions on certain 4-manifolds.
