String Theory on AdS Orbifolds
We consider worldsheet string theory on ZN orbifolds of AdS3 associated with conical singularities. If the orbifold action includes a similar twist of S3, supersymmetry is preserved, and there is a moduli space of vacua arising from blowup modes of the orbifold singularity. We exhibit the spectrum, including the properties of twisted sectors and states obtained by fractional spectral flow. A su...
متن کاملM/F theory orbifolds
We consider M-theory on (T ×R)/Zn with M5 branes wrapped on R2. One can probe this background with M5 branes wrapped on T2. The theories on the probes provide many new examples of N = 2 field theories without Lagrangian description. All these theories have Coulomb branches, and we find the corresponding SeibergWitten curves. The exact solution is encoded in a Hitchin system on an orbifolded tor...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملVacua of M-theory and String Theory
We argue that supersymmetric higher-dimension operators in the effective actions of M-theory and IIB string theory do not affect the maximally supersymmetric vacua: adS4 × S 7 and adS7 × S 4 in Mtheory and adS5 × S 5 in IIB string theory. All these vacua are described in superspace by a fixed point with all components of supertorsion and supercurvature being supercovariantly constant. This foll...
متن کاملTopological Terms in String Theory on Orbifolds
We study toroidal orbifold models with topologically invariant terms in the path integral formalism and give physical interpretations of the terms from an operator formalism point of view. We briefly discuss a possibility of a new class of modular invariant orbifold models.
