# A gluing formula for families Seiberg–Witten invariants

@article{Baraglia2018AGF, title={A gluing formula for families Seiberg–Witten invariants}, author={David Baraglia and Hokuto Konno}, journal={arXiv: Differential Geometry}, year={2018} }

We prove a gluing formula for the families Seiberg-Witten invariants of families of $4$-manifolds obtained by fibrewise connected sum. Our formula expresses the families Seiberg-Witten invariants of such a connected sum family in terms of the ordinary Seiberg-Witten invariants of one of the summands, under certain assumptions on the families. We construct some variants of the families Seiberg-Witten invariants and prove the gluing formula also for these variants. One variant incorporates a…
