Comments on M Theory Dynamics on G 2 Holonomy Manifolds
We study the dynamics of M-theory on G2 holonomy manifolds, and consider in detail the manifolds realized as the quotient of the spin bundle over S by discrete groups. We analyse, in particular, the class of quotients where the triality symmetry is broken. We study the structure of the moduli space, construct its defining equations and show that three different types of classical geometries are...
متن کاملAnomalies in M - theory on singular G 2 - manifolds
When M-theory is compactified on G2-holonomy manifolds with conical singularities, charged chiral fermions are present and the low-energy fourdimensional theory is potentially anomalous. We reconsider the issue of anomaly cancellation, first studied by Witten. We propose a mechanism that provides local cancellation of all gauge and mixed gauge-gravitational anomalies, i.e. separately for each c...
متن کاملFluxes in M-theory on 7-manifolds and G structures
We consider warp compactifications of M-theory on 7-manifolds in the presence of 4-form fluxes and investigate the constraints imposed by supersymmetry. As long as the 7-manifold supports only one Killing spinor we infer from the Killing spinor equations that non-trivial 4-form fluxes will necessarily curve the external 4-dimensional space. On the other hand, if the 7-manifold has at least two ...
متن کاملM-theory on manifolds . . .
In 1982 the concept of holonomy was introduced into Kaluza-Klein theory as a way of counting the number of supersymmetries surviving compactification. The first non-trivial example was provided by D = 11 supergravity on the squashed S 7 , whose G 2 holonomy yields N = 1 in D = 4. In 1983 another example was provided by D = 11 supergravity on K3, whose SU (2) holonomy yields half the maximum sup...
متن کاملComments on M - theory on G 2 manifolds and ( p , q ) webs
Using a reformulation of the method of (p, q) webs, we study the four-dimensional N = 1 quiver theories from M-theory on seven-dimensional manifolds with G2 holonomy. We first construct such manifolds as U(1) quotients of eight-dimensional toric hyper-Kähler manifolds, using N = 4 supersymmetric sigma models. We show that these geometries, in general, are given by real cones on S bundles over c...
