Fuzzy spaces are obtained by quantizing adjoint orbits of compact semi-simple Lie groups. Fuzzy spheres emerge from quantizing S-2 and are associated with the group SU(2) in this manner. They are useful for regularizing quantum field theories and modeling space-times by noncommutative manifolds. We show that fuzzy spaces are Hopf algebras and in fact have more structure than the latter. They are thus candidates for quantum symmetries. Using their generalized Hopf algebraic structures, we can also model processes where one fuzzy space splits into several fuzzy spaces. For example we can discuss the quantum transition where the fuzzy sphere for angular momentum J splits into fuzzy spheres for angular momenta K and L.

Mass spectra of heavy quarkonia and B-c decay constant for static scalar-vector interactions with relativistic kinematics Ikhdair, SM; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2005-11-10) We reproduce masses of the self-conjugate and non-self-conjugate mesons in the context of the spinless Salpeter equation taking into account the relativistic kinematics and the quark spins. The hyperfine splittings for the 2S charmonium and IS bottomonium are also calculated. Further, the pseudoscalar and vector decay constants of the Be meson and the unperturbed radial wave function at the origin are also calculated. We have obtained a local equation with a complete relativistic corrections to a class of t...
Interacting quantum topologies and the quantum Hall effect Balachandran, A. P.; Gupta, Kumar S.; Kürkcüoğlu, Seçkin (World Scientific Pub Co Pte Lt, 2008-04-10) The algebra of observables of planar electrons subject to a constant background magnetic field B is given by A(theta)(R-2) circle times A(theta)(R-2) (theta = -4/eB), the product of two mutually commuting Moyal algebras. It describes the free Hamiltonian and the guiding center coordinates. We argue that A(theta)(R-2) itself furnishes a representation space for the actions of these two Moyal algebras, and suggest physical arguments for this choice of the representation space. We give the proper setup to coup...
PROPERTIES OF BC-MESON IN QCD SUM-RULES Alıyev, Tahmasıb (Springer Science and Business Media LLC, 1992-06-01) We have studied the masses of the scalar, pseudoscalar and vector states of B(c)-meson and their decay constants in the framework of the QCD sum rules.

SEMICLASSICAL BLACK HOLES WITH LARGE N RESCALING AND INFORMATION LOSS PROBLEM Yeom, Dong-Han; Zoe, Heeseung (World Scientific Pub Co Pte Lt, 2011-07-30) We consider semiclassical black holes and related rescalings with N massless fields. For a given semiclassical solution of an N = 1 universe, we can find other solution of a large N universe by the rescaling. After the rescaling, any curvature quantity takes a sufficiently small value without changing its causal structure. Via the rescaling, we argue that black hole complementarity for semiclassical black holes cannot provide a fundamental resolution of the information loss problem, and the violation of bla...
SENSITIVITY OF THE STOKES PARAMETERS IN THE DECAY B-]S-GAMMA-G TO THE MODEL OF FCNC Alıyev, Tahmasıb; TURAN, G (Springer Science and Business Media LLC, 1995-01-01) We calculated the Stokes parameters which characterize the polarization properties of the photons produced in the decay b-->s gamma g in the framework of the Standard Model (SM) and Two Higgs Doublet Model (2HDM). It is shown that the Stokes parameter xi 3, which defines the linear photon polarization with a polarization vector in the decay plane, is very sensitive to the parameters of the above-mentioned models. The predicted values of xi(3) are large enough (in some cases it achieves the maximum possible ...
