R**4 corrections to conifolds and G(2)-holonomy spaces
(Elsevier, 2002)Motivated by examples that appeared in the context of string theory?gauge theory duality, we consider corrections to supergravity backgrounds induced by higher derivative (R4+cdots, three dots, centered) terms in superstring ... -
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 ... -
Radial and orbital excitations of static-light mesons
(2007)We present results for the spectrum of static-light mesons from Nf = 2 lattice QCD. These results were obtained using all-to-all light quark propagators on an anisotropic lattice, yielding an improved signal resolution ... -
Random sampling and large deviations
(Trinity College (Dublin, Ireland). School of Mathematics, 2001)In this thesis, we are concerned with the effect of randomly sampling a stochastic process. We consider two stochastic processes: the underlying process, {Xt}tεT and the observation process {Tn}nεN, a strictly increasing ... -
Ranges of bimodule projections and conditional expectations
(Trinity College (Dublin, Ireland). School of Mathematics, 2011)The algebraic theory of comer subrings introduced by Lam (as an abstraction of the properties of Peirce corners eRe of a ring R associated with an idempotent e E R) are investigated here in the context of Banach and ... -
Remarks on the rigidity of CR-manifolds
(NUMDAM, 2006)A method is proposed to obtain examples of smooth CR-manifolds whose local stability group is neither a Lie group nor infinite-dimensional. -
Removing fermion doublers in chiral gauge theories on the lattice
(Elsevier, 1994)A method for removing fermion doublers in anomaly free chiral gauge theories on the lattice is proposed. It is proven that the resulting continuum theory is gauge invariant and does not require noninvariant counterterms ... -
Resonances and lattice field theory
(Trinity College (Dublin, Ireland). School of Mathematics, 2012)In this thesis, we look at the extraction of resonance parameters in lattice field theory. In particular we detail two major methods of dealing with resonances and consider them in a perturbative and nonpertnrbative ... -
Robust layer-resolving methods for various Prandtl problems
(Trinity College (Dublin, Ireland). School of Mathematics, 2005)In this thesis we deal with four Prandtl boundary layer problems for incompressible laminar flow. When the Reynolds and Prandtl numbers are large the solution of each problem has parabolic boundary layers. For each problem ... -
Rotating string solutions: AdS/CFT duality in non-supersymmetric sectors
(Elsevier, 2003)We find the minimal energy solution describing a folded closed string located at the center of AdS5 and rotating simultaneously in two planes in S5 with two arbitrary SO(6) angular momenta J1 and J2. In the case when J1 ... -
S wave bottomonium states moving in a quark-gluon plasma from lattice NRQCD
(2013)We extend our study of bottomonium spectral functions in the quark-gluon plasma to nonzero momentum. We use lattice QCD simulations with two flavours of light quark on highly anisotropic lattices and treat the bottom quark ... -
The S-matrix of String Bound States
(2008)We find the S-matrix which describes the scattering of two-particle bound states of the light-cone string sigma model on AdS5xS5. We realize the M-particle bound state representation of the centrally extended su(2|2) algebra ... -
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. -
Scalar quartic couplings in type IIB supergravity on AdS(5) x S(5)
(2000)All quartic couplings of scalar fields sI that are dual to extended chiral primary operators in N = 4 SYM4 are derived by using the covariant equations of motion for type IIB supergravity on AdS5 ? S5. It is shown that ...
