Abstract

On a smooth closed oriented 44-manifold MM with a smooth action of a finite group GG on a Spinc^c structure, GG-monopole invariant is defined by "counting" GG-invariant solutions of Seiberg-Witten equations for any GG-invariant Riemannian metric on MM. We compute GG-monopole invariants on some GG-manifolds. For example, the connected sum of kk copies of a 4-manifold with nontrivial mod 2 Seiberg-Witten invariant has nonzero Zk\Bbb Z_k-monopole invariant mod 2, where the Zk\Bbb Z_k-action is given by cyclic permutations of kk summands.
