AbstractGeometric Engineering is an important tool to construct a large class of non-Lagrangian theories in various dimensions. If a gauge algebra admits discrete automorphisms, there is the possibility to twist by them when performing a circle reduction. Since F-theory is related to M-theory by a circle reduction, and M-theory is sensitive to the full geometry, this begs the question which geo...
