Anomalous Couplings in M-Theory and String Theory
We explore how various anomaly-cancelling terms in M-theory and string theory transform non-trivially into each other under duality. Specifically, we study the phenomenon in which bulk terms in M-theory get mapped to brane worldvolume terms in string theory. The key mathematical ingredient is G-index theory.
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...

15 صفحه اولVacua 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 کاملString/M Theory
This is a brief review of the present status, of some recent developments and of the open challenges in string/M theory.† 1. Why string theory The main claim of string theory is that it cures the singular short-distance behaviour of Einstein gravity, without giving up the fundamental laws of quantum mechanics. Although this is far from established, there are serious indications that the claim c...
