The WZNW Model By A Perturbation Of Witten’s Conformal Solution
The WZNW model at the Witten conformal point is perturbed by the σ-model term. It is shown that in the large level k limit the perturbed WZNW system with negative k arrives at the WZNW model with positive k.
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
The WZNW Model As An Integrable Perturbation Of The Witten Conformal Point
We show that the WZNW model with arbitrary σ-model coupling constant may be viewed as a σ-model perturbation of the WZNW theory around the Witten conformal point. In order for the σ-model perturbation to be relevant, the level k of the underlying affine algebra has to be negative. We prove that in the large |k| limit the perturbed WZNW system with negative k flows to the conformal WZNW model wi...

investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
