Reflections on the Matter of 3d $\mathcal{N}=1$ Vacua and Local $Spin(7)$ Compactifications

Mirjam Cvetič, Jonathan J. Heckman, Ethan Torres +1

We use Higgs bundles to study the 3d $\mathcal{N}=1$ vacua obtained from M-theory compactified on a local $Spin(7)$ space given as a four-manifold $M_4$ of ADE singularities with…
