چکیده
We study M-theory on two classes of manifolds of Spin(7) holonomy that are developing an isolated conical singularity. We construct explicitly a new class of Spin(7) manifolds and analyse in detail the topology of the corresponding classical spacetimes. We discover also an intricate interplay between various anomalies in M-theory, string theory, and gauge theory within these models, and in particular find a connection between half-integral G-fluxes in M-theory and Chern-Simons terms of the N = 1, D = 3 effective theory. email: [email protected] email: [email protected]

It is argued that M-theory compactifications on any of Joyce's Spin(7) holonomy 8-manifolds are dual to compactifications of het-erotic string theory on Joyce 7-manifolds of G 2 holonomy.
متن کاملString and M-theory Deformations of Manifolds with Special Holonomy
The R-type corrections to ten and eleven dimensional supergravity required by string and M-theory imply corrections to supersymmetric supergravity compactifications on manifolds of special holonomy, which deform the metric away from special holonomy. Nevertheless, in many such cases, including Calabi-Yau compactifications of string theory and G2-compactifications of M-theory, it has been shown ...

In this note we study warped compactifications of M -theory on manifolds of Spin(7) holonomy in the presence of background 4-form flux. The explicit expression for the superpotential can be given in terms of the self-dual Cayley calibration on the Spin(7) manifold, in agreement with the general formula proposed in hep-th/9911011.

We show that the moduli spaces of associative submanifolds of a G 2 manifold (and Cayley submanifolds of a Spin(7) manifold) can be perturbed to smooth manifolds. By using connections as natural parameters and by constraining them with an additional equation and using Seiberg-Witten theory we can make them compact, and hence assign local invariants to these submanifolds. The local equations of ...
