Tops as Building Blocks for G2 Manifolds

High Energy Physics - Theory 2017-10-16 v3 Algebraic Geometry

Abstract

A large number of examples of compact G2G_2 manifolds, relevant to supersymmetric compactifications of M-Theory to four dimensions, can be constructed by forming a twisted connected sum of two appropriate building blocks times a circle. These building blocks, which are appropriate K3K3-fibred threefolds, are shown to have a natural and elegant construction in terms of tops, which parallels the construction of Calabi-Yau manifolds via reflexive polytopes.
