New Spin(7) Holonomy Metrics Admiting G 2 Holonomy Reductions and M-theory/iia Dualities
We construct several Spin(7) holonomy metrics which admits a G2 holonomy reduction along one isometry. The resulting G2 holonomy metrics admit a further reduction to a 6-dimensional Kahler metric, therefore realizing the pattern Spin(7) → G2 → (Kahler) proposed in [26] and which describe an M-theory/IIA superstring duality. An infinite class of such metrics are found, which are locally R3-fibra...
متن کاملNew Spin ( 7 ) holonomy metrics admitting G 2 holonomy reductions and M - theory / IIA dualities
As is well known, when D6 branes wrap a special lagrangian cycle on a non compact CY 3-fold in such a way that the internal string frame metric is Kahler there exists a dual description, which is given in terms of a purely geometrical eleven dimensional background with an internal metric of G2 holonomy. It is also known that when D6 branes wrap a coassociative cycle of a non compact G2 manifold...
متن کاملRational Conformal Field Theories With G 2 Holonomy
We study conformal field theories for strings propagating on compact, seven-dimensional manifolds with G 2 holonomy. In particular, we describe the construction of rational examples of such models. We argue that analogues of Gepner models are to be constructed based not on N = 1 minimal models, but on Z 2 orbifolds of N = 2 models. In Z 2 orbifolds of Gepner models times a circle, it turns out ...
متن کاملIntersecting branes and 7 - manifolds with G 2 holonomy
In this talk I discuss intersecting brane configurations coming from explicit metrics with G2 holonomy. An example of a 7-manifold which representing a R 3 bundle over a self-dual Einstein space is described and the potential appearing after compactification over the 6-d twistor space is derived.
متن کاملComments 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...
