SO(N) invariant Wess-Zumino action and its quantization
(Springer Verlag, 1996)A consistent quantization procedure of anomalous chiral models is discussed. It is based on a modification of the classical action by adding Wess-Zumino terms. The SO(3) invariant WZ action for the SU(3) model is constructed. ... -
Canonical quantization of the degenerate WZ action including chiral interaction with gauge fields
(World Scientific, 1996)Canonical quantization of the Wess-Zumino (WZ) model including chiral interaction with gauge field is considered for the case of a degenerate action. The two-dimensional SU(2) Yang-Mills model and the four-dimensional ... -
Tetrahedral and cubic monopoles
(Springer Science + Business Media, 1996)Using a numerical implementation of the ADHMN construction, we compute the fields and energy densities of a charge three monopole with tetrahedral symmetry and a charge four monopole with octahedral symmetry. We then ... -
The scalar glueball from a tadpole-improved action
(Elsevier, 1996)The scalar glueball mass and the string tension are computed in lattice SU(3) gauge theory with the aim of establishing the effectiveness of the improved action approach in removing finite-spacing artifacts. -
New hyper-Kaehler manifolds by fixing monopoles
(American Physical Society, 1997)The construction of new hyper-Ka?hler manifolds by taking the infinite monopole mass limit of certain Bogomol?nyi-Prasad-Sommerfield monopole moduli spaces is considered. The one-parameter family of hyper- Ka?hler manifolds ... -
Effect of tree-level and mean-field improvement on the light-hadron spectrum in quenched QCD
(American Physical Society, 1997)We compute the light-hadron mass spectrum at b55.7 using the O(a)-improved Sheikholeslami-Wohlert fermion action with two choices of the clover coefficient: the classical value c51 and a mean-field or tadpole-improved ... -
Efficient glueball simulations on anisotropic lattices
(American Physical Society, 1997)Monte Carlo results for the low-lying glueball spectrum using an improved, anisotropic action are presented. Ten simulations at lattice spacings ranging from 0.2 to 0.4 fm and two different anisotropies have been performed ... -
SU(3) glueballs on coarse, anisotropic lattices
(Elsevier, 1997)Results from a calculation of the low-lying glueball spectrum of pure-gauge SU(3) are used as a test of the effectiveness of improved discretisation schemes in reducing finite spacing errors. Glueball masses are extracted from ... -
Euromath system: alphabets and fonts
(Institute of Computational Technologies, 1997)We describe some of the principles behind the design of the Euromath system, concentrating on some aspects that are needed to explain how the system deals with alphabets and fonts and are not immediately apparent from a ... -
Physical phase space of lattice Yang-Mills theory and the moduli space of flat connections on a Riemann surface
(Springer Verlag, 1997)It is shown that the physical phase space of -deformed Hamiltonian lattice Yang-Mills theory, which was recently proposed in refs.[1,2], coincides as a Poisson manifold with the moduli space of flat connections on a ... -
Elliptic Ruijsenaars-Schneider model via the Poisson reduction of the Affine Heisenberg Double
(Institute of Physics, 1997)It is shown that the elliptic Ruijsenaars-Schneider model can be obtained from the affine Heisenberg Double by means of the Poisson reduction procedure. The dynamical r-matrix naturally appears in the construction. -
Elliptic Ruijsenaars-Schneider model from the cotangent bundle over the two-dimensional current group
(American Institute of Physics, 1997)It is shown that the elliptic Ruijsenaars?Schneider model can be obtained from the cotangent bundle over the two-dimensional current group by means of the Hamiltonian reduction procedure. -
SU(N) monopoles and Platonic symmetry
(American Institute of Physics, 1997)We discuss the ADHMN construction for SU(N) monopoles and show that a particular simplification arises in studying charge N?1 monopoles with minimal symmetry breaking. Using this we construct families of tetrahedrally ... -
Coarse lattice results for glueballs and hybrids
(Elsevier, 1998)A review of new results from lattice simulations of glueballs and heavy-quark hybrid mesons is presented. -
Spectroscopy of Bs and Ds mesons
(Elsevier, 1998)We study Bs and Ds spectroscopy in quenched lattice QCD using the Fermilab approach to heavy quarks. We obtain results at four lattice spacings, a, using O(a)-improved Wilson quarks. We compare and contrast the various ... -
Domains of polyhedral type and boundary extensions of biholomorphisms
(1998)For D, D? analytic polyhedra in Cn, it is proven that a biholomorphic mapping f : D ! D? extends holomorphically to a dense boundary subset under certain condition of general position. This result is also extended to ... -
Fourier analysis, multiresolution analysis and dilation equations
(Trinity College (Dublin, Ireland). School of Mathematics, 1998)This thesis has essentially two parts. The first two chapters are an introduction to the related areas of Fourier analysis, multiresolution analysis and wavelets. Dilation equations arise in the context of multi resolution ... -
R-matrix quantization of the elliptic Ruijsenaars-Schneider model
(Springer Verlag, 1998)It is shown that the classical L-operator algebra of the elliptic Ruijsenaars-Schneider model can be realized as a subalgebra of the algebra of functions on the cotangent bundle over the centrally extended current group ... -
Virasoro amplitude from the S(N) R**24 orbifold sigma model
(Springer, 1998)Four tachyon scattering amplitude is derived from the SNR24 orbifold sigma model in the large N limit. The closed string interaction is described by a vertex which is a bosonic analog of the supersymmetric one, recently ...
