Matrix Strings in Weakly Curved Background Fields
We investigate further the recent proposal for the form of the Matrix theory action in weak background fields. We perform DVV reduction to the multipleD0–brane action in order to find the Matrix string theory action for multiple fundamental strings in curved but weak NS–NS and R–R backgrounds. This matrix sigma model gives a definite prescription on how to deal with R–R fields with an explicit ...
متن کاملDuality of string amplitudes in a curved background
We initiate a program to study the relationship between the target space, the spectrum and the scattering amplitudes in string theory. We consider scattering amplitudes following from string theory and quantum field theory on a curved target space, which is taken to be the SU(2) group manifold, with special attention given to the duality between contributions from different channels. We give a ...
متن کاملT - Duality and the Weakly Coupled Heterotic String
T-duality is a symmetry of the heterotic string to all orders in string perturbation theory. This results in an effective four dimensional supergravity theory with desirable features for phenomenology. T-duality, as well as, generically, an anomalous U(1), is broken by quantum anomalies of the effective field theory. The structure of the full anomaly is presented, and the mechanisms for anomaly...
متن کاملCategorial Background for Duality Theory
In the paper, we develop the notation of lattice-wise categories as concrete categories (see [10]) of lattices. Namely, the categories based on [24] with lattices as objects and at least monotone maps between them as morphisms. As examples, we introduce the categories UPS, CONT, and ALG with complete, continuous, and algebraic lattices, respectively, as objects and directed suprema preserving m...
متن کاملInteracting Quantum Fields on a Curved Background
A renormalized perturbative expansion of interacting quantum fields on a globally hyperbolic spacetime is performed by adapting the Bogoliubov Epstein Glaser method to a curved background. The results heavily rely on techniques from microlocal analysis, in particular on Radzikowski’s characterization of Hadamard states by wave front sets of Wightman functions. Quantum field theory on a curved b...
