this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Exact classical solutions of nonlinear sigma models on supermanifolds
We study two-dimensional nonlinear sigma models with target spaces being the complex super Grassmannian manifolds, that is, coset supermanifolds G(m, p|n, q) ∼= U(m|n)/[U(p|q) ⊗ U(m − p|n − q)] for 0 ≤ p ≤ m, 0 ≤ q ≤ n and 1 ≤ p + q. The projective superspace CP is a special case of p = 1, q = 0. For the two-dimensional Euclidean base space, a wide class of exact classical solutions (or harmoni...
متن کاملClassical solution of a sigma–model in curved background
We have solved a σ–model in curved background using the fact that the Poisson–Lie T-duality can transform the curved background into the flat one. For finding solution of the flat model we have used transformation of coordinates that makes the metric constant. The T-duality transform was then explicitly performed.
متن کاملExact Supersymmetric String Solutions in Curved Gravitational Backgrounds
We construct a new class of exact and stable superstring solutions based on N = 4 superconformal world-sheet symmetry. In a subclass of these, the full spectrum of string excitations is derived in a modular-invariant way. In the weak curvature limit, our solutions describe a target space with nontrivial metric and topology, and generalize the previously known (semi) wormhole. The effective fiel...
متن کاملPoisson–Lie T–plurality of three–dimensional conformally invariant sigma models
Starting from the classification of 6–dimensional real Drinfeld doubles and their decomposition into Manin triples we construct 3–dimensional Poisson–Lie T–dual or more precisely T–plural sigma models. Of special interest are those that are conformally invariant. Examples of models that satisfy vanishing β–function equations with zero dilaton are presented and their duals are calculated. It tur...
