Aspects of the q–deformed Fuzzy Sphere
نویسنده
چکیده
These notes are a short review of the q–deformed fuzzy sphere S2 q,N , which is a “finite” noncommutative 2–sphere covariant under the quantum group Uq(su(2)). We discuss its real structure, differential calculus and integration for both real q and q a phase, and show how actions for Yang–Mills and Chern–Simons–like gauge theories arise naturally. It is related to D-branes on the SU(2)k WZW model for q = exp( iπ k+2).

Quantum Field Theory on the q–deformed Fuzzy Sphere
We discuss the second quantization of scalar field theory on the q–deformed fuzzy sphere S2 q,N for q ∈ IR, using a path–integral approach. We find quantum field theories which are manifestly covariant under Uq(su(2)), have a smooth limit q → 1, and satisfy positivity and twisted bosonic symmetry properties. Using a Drinfeld twist, they are equivalent to ordinary but slightly “nonlocal” QFT’s o...
متن کاملField Theory on the q – Deformed Fuzzy Sphere
We study the q–deformed fuzzy sphere, which is related to D-branes on SU(2) WZW models, for both real q and q a root of unity. We construct for both cases a differential calculus which is compatible with the star structure, study the integral, and find a canonical frame of one–forms. We then consider actions for scalar field theory, as well as for Yang–Mills and Chern–Simons–type gauge theories...
متن کاملFuzzy Torus and q-Deformed Lie Algebra
It will be shown that the defining relations for fuzzy torus and deformed (squashed) sphere proposed by J. Arnlind, et al (hep-th/0602290) can be rewriten as a new algebra which contains q-deformed commutators. The quantum parameter q (|q| = 1) is a function of ~. It is shown that the q → 1 limit of the algebra with the parameter μ < 0 describes fuzzy S and that the squashed S with q 6= 1 and μ...
متن کاملField Theory on the q–deformed Fuzzy Sphere II: Quantization
We study the second quantization of field theory on the q–deformed fuzzy sphere for q ∈ R. This is performed using a path integral over the modes, which generate a quasiassociative algebra. The resulting models have a manifest Uq(su(2)) symmetry with a smooth limit q → 1, and satisfy positivity and twisted bosonic symmetry properties. A systematic way to calculate n–point correlators in perturb...
متن کاملON ( $alpha, beta$ )-FUZZY Hv-IDEALS OF H_{v}-RINGS
Using the notion of “belongingness ($epsilon$)” and “quasi-coincidence (q)” of fuzzy points with fuzzy sets, we introduce the concept of an ($ alpha, beta$)- fuzzyHv-ideal of an Hv-ring, where , are any two of {$epsilon$, q,$epsilon$ $vee$ q, $epsilon$ $wedge$ q} with $ alpha$ $neq$ $epsilon$ $wedge$ q. Since the concept of ($epsilon$, $epsilon$ $vee$ q)-fuzzy Hv-ideals is an important and ...
