The Sound of M-Theory
We consider sound propagation on M5and M2-branes in the hydrodynamic limit. In particular, we look at the low energy description of a stack of N M-branes at finite temperature. At low energy, the M-branes are well described, via the AdS/CFT correspondence, in terms of classical solutions to the eleven dimensional supergravity equations of motion. From this gravitational description, we calculat...
متن کاملOptimality Theory and Sound Change
Since Kiparsky (1968) it has been standard practice in generative phonology to account for sound change by means of rule addition, rule simplification, rule reordering and rule loss. Given that the phonological rule as such no longer exists in recently proposed constraint-based theories of phonology, such as Optimality Theory (cf. Prince and Smolensky (1993), McCarthy and Prince (1993a and b), ...
متن کاملThe M(atrix) Model of M-theory
These lecture notes give a pedagogical and (mostly) self-contained review of some basic aspects of the Matrix model of M-theory. The derivations of the model as a regu-larized supermembrane theory and as the discrete light-cone quantization of M-theory are presented. The construction of M-theory objects from matrices is described, and gravitational interactions between these objects are derived...
متن کاملCoupling of M–branes in M–theory
Coupling of a membrane and a five-brane to the bosonic sector of D = 11 supergravity is considered. The five–brane is a dyonic object which carries both an electric and a magnetic charge of the D = 11 three-form gauge field A, and it couples not only to A but also minimally couples to a six-form field A dual to A. This implies that the 5-brane should more naturally couple to a version of D = 11...
متن کاملCompactifications of M-theory
We discuss Poincaré three-brane solutions in D = 5 M-Theory compactifications on Calabi-Yau (CY) threefolds with G-fluxes. We show that the vector moduli freeze at an attractor point. In the case with background flux only, the spacetime geometry contains a zero volume singularity with the three-brane and the CY space shrinking simultaneously to a point. This problem can be avoided by including ...
