Universal Hypermultiplet Metrics
Some instanton corrections to the universal hypermultiplet moduli space metric of the type-IIA string theory compactified on a Calabi-Yau threefold arise due to multiple wrapping of BPS membranes and fivebranes around certain cycles of Calabi-Yau. The classical universal hypermultipet metric is locally equivalent to the Bergmann metric of the symmetric quaternionic space SU(2, 1)/U(2), whereas ...
متن کاملQuantum Geometry of the Universal Hypermultiplet
The universal hypermultiplet moduli space metric in the type-IIA superstring theory compactified on a Calabi-Yau threefold is related to integrable systems. The instanton corrections in four dimensions arise due to multiple wrapping of BPS membranes and fivebranes around certain (supersymmetric) cycles of Calabi-Yau. The exact (nonperturbative) metrics can be calculated in the special cases of ...
متن کاملD-instantons and Universal Hypermultiplet
The quantum non-perturbative geometry of the toy model of the universal hyper-multiplet is discussed. We consider the simple case when the D-instantons, originating from the Calabi-Yau wrapped D2-branes, preserve a U(1) × U(1) symmetry of the universal hypermultiplet moduli space. Our aim is to find some quaternionic solutions to the effective NLSM metric of the universal hypermultiplet, which ...
متن کاملInstanton Solutions for the Universal Hypermultiplet
We expand our previous analysis on fivebrane and membrane instanton solutions in the universal hypermultiplet, including near-extremal multi-centered solutions and mixed fivebranemembrane charged instantons. The results are most conveniently described in terms of a double-tensor multiplet.
متن کاملLoop Corrections To The Universal Hypermultiplet,” Phys
The universal hypermultiplet arises as a subsector of every Calabi-Yau compactifica-tion of M-theory or Type II string theory. Classically its moduli space is the quaternionic space SU (2, 1)/U (2). We show that this moduli space receives a one-loop correction proportional to the Euler character of the Calabi-Yau, which can locally be absorbed by a certain constant shift of the fields. The corr...
