The Witten-style conjecture for finite-order mapping tori

Let XX be a smooth closed oriented 44-manifold such that

H(X;Z)=H(S1×S3;Z)andH(X~;Q)=H(S3;Q),H_*(X;\mathbb Z)=H_*(S^1\times S^3;\mathbb Z)\quad\text{and}\quad H_*(\widetilde X;\mathbb Q)=H_*(S^3;\mathbb Q),

where X~\widetilde X is the universal abelian cover of XX. The invariants λSW(X)\lambda_{\,\rm{SW}}(X) and λFO(X)\lambda_{\,\rm{FO}}(X) are respectively the Seiberg–Witten and Furuta–Ohta gauge-theoretic invariants of XX. The Witten-style conjecture. For any XX satisfying these conditions,

λSW(X)=λFO(X).\lambda_{\,\rm{SW}}(X)=-\lambda_{\,\rm{FO}}(X).

This conjecture proposes equality, up to sign, between the Seiberg–Witten and Donaldson-type invariants for homology S1×S3S^1\times S^3 manifolds. It is motivated by the Witten conjecture relating Donaldson and Seiberg–Witten theories, but the supplied text gives no resolution status.
