M-Theory on Manifolds with G2 Holonomy
We study M-theory on G2 holonomy spaces that are constructed by dividing a seven-torus by some discrete symmetry group. We classify possible group elements that may be used in this construction and use them to find a set of possible orbifold groups that lead to co-dimension four singularities. We describe how to blow up such singularities, and then derive the moduli Kähler potential for M-theor...
متن کاملM-theory on manifolds of G2 homology: . . .
In 1981, covariantly constant spinors were introduced into Kaluza-Klein theory as a way of counting the number of supersymmetries surviving compactification. These are related to the holonomy group of the compactifying manifold. The first non-trivial example was provided in 1982 by D = 11 supergravity on the squashed S 7 , whose G 2 holonomy yields N = 1 in D = 4. In 1983 another example was pr...
متن کاملM-theory Compactifications on Manifolds with G2 Structure
In this paper we study M-theory compactifications on manifolds of G2 structure. By computing the gravitino mass term in four dimensions we derive the general form for the superpotential which appears in such compactifications and show that beside the normal flux term there is a term which appears only for non-minimal G2 structure. We further apply these results to compactifications on manifolds...
متن کاملF-theory Duals of M-theory on G2 Manifolds from Mirror Symmetry
Using mirror pairs (M3,W3) in type II superstring compactifications on Calabi-Yau threefols, we study, geometrically, F-theory duals of M-theory on seven manifolds with G2 holonomy. We first develop a new way for getting Landau Ginzburg (LG) CalabiYau threefols W3, embedded in four complex dimensional toric varieties, mirror to sigma model on toric Calabi-Yau threefolds M3. This method gives di...
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...
