Superpotential of the M -theory conifold and type IIA string theory

چکیده
The membrane instanton superpotential for M-theory on the G 2 holonomy manifold given by the cone on S 3 × S 3 is given by the dilogarithm and has Heisenberg monodromy group in the quantum moduli space. We compare this to a Heisenberg group action on the type IIA hypermultiplet moduli space for the universal hypermultiplet, to metric corrections from membrane instantons related to a twisted dilogarithm for the deformed conifold and to a flat bundle related to a conifold period, the Heisenberg group and the dilogarithm appearing in five-dimensional Seiberg/Witten theory.

Conifold Cosmologies in IIA String Theory
We discuss the extension of our recent work on M-theory conifold cosmologies to general conifold transitions and type-IIA string theory.
متن کاملAspects of Moduli Stabilisation in String and M-theory
In this thesis we study compactifications of type II string theories and M-theory to four dimensions. We construct the four-dimensional N = 2 supergravities that arise from compactifications of type IIA string theory and M-theory on manifolds with SU(3)structure. We then study their potential for moduli stabilisation and give explicit examples where all the moduli are stabilised. We also study ...
متن کاملHolonomy Spaces from Invariant Three - Forms
We construct several new G2 holonomy metrics that play an important role in recent studies of geometrical transitions in compactifications of M-theory to four dimensions. In type IIA string theory these metrics correspond to D6 branes wrapped on the threecycle of the deformed conifold and the resolved conifold with two-form RR flux on the blown-up two-sphere, which are related by a conifold tra...
متن کاملOn Realising N=1 Super Yang-mills in M Theory
Pure N =1 super Yang-Mills theory can be realised as a certain low energy limit of M theory near certain singularities in G 2-holonomy spaces. For SU(n) and SO(2n) gauge groups these M theory backgrounds can be regarded as strong coupling limits of wrapped D6-brane configurations in Type IIA theory on certain non-compact Calabi-Yau spaces such as the deformed conifold. Various aspects of such r...
متن کاملSolitons, Superpotentials and Calibrations
In this paper we study several issues related to the generation of superpotential induced by background Ramond-Ramond fluxes in compactification of Type IIA string theory on Calabi-Yau four-folds. Identifying BPS solitons with D-branes wrapped over calibrated submanifolds in a Calabi-Yau space, we propose a general formula for the superpotential and justify it comparing the supersymmetry condit...
