SKK groups of manifolds and non-unitary invertible TQFTs

Renee S. Hoekzema, Luuk Stehouwer, Simona Veselá

This work considers the computation of controllable cut-and-paste groups ${\mathrm{SKK}}_n^{\xi }$ of manifolds with tangential structure $\xi :B_n\to B{O}_n$. To this end, we apply the work o…
