A topological quantum field theory for $\mathrm{Spin}(7)$-instantons

Rafael Herrera, Sergio A. Holguin Cardona, Alexander Quintero Velez

We construct a topological quantum field theory based on the moduli space of $\mathrm{Spin}(7)$-instantons on 8-dimensional manifolds. Using the Mathai-Quillen formalism, we derive…
