Spinon Decomposition and Yangian Structure
We present a ‘spinon formulation’ of the ̂ SU(n)1 Wess-Zumino-Witten models. Central to this approach are a set of massless quasi-particles, called ‘spinons’, which transform in the representation n of su(n) and carry fractional statistics of angle θ = π/n. Multi-spinon states are grouped into irreducible representations of the yangian Y (sln). We give explicit results for the su(n) content of t...
متن کاملSpinon Basis for Higher Level Su (2) Wzw Models
We propose a spinon basis for the integrable highest weight modules of ŝl2 at levels k ≥ 1, and discuss the underlying Yangian symmetry. Evaluating the characters in this spinon basis provides new quasiparticle type expressions for the characters of these integrable modules, and explicitly exhibits the structure of an RSOS times a Yangian part, known e.g. from S-matrix results. We briefly discu...
متن کاملYangian, Truncated Yangian and Quantum Integrable Models
Based on the RTT relation for the given rational R-matrix the Yangian and truncated Yangian are discussed. The former can be used to generate the longrange interaction models, whereas the latter can be related to the GoryachevChaplygin(GC) gyrostat. The trigonometric extension of the Goryachev-Chaplygin gyrostat has also been shown.

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

We review several fermionic-type character formulae for the characters of the integrable highest weight modules of ŝln at level l = 1, and explain how they arise from a spinon basis for these modules. We also review how the Yangian Y (sln) acts on the integrable (ŝln)1 modules and we decompose the characters with respect to this Y (sln) action. ADP-96-36/M47 ITFA-97-08 q-alg/9703021 † To appear...
