    • Quark-gluon plasma phenomenology from anisotropic lattice QCD 

      RYAN, SINEAD (2016)
      The FASTSUM collaboration has been carrying out simulations of N f = 2 + 1 QCD at nonzero temperature in the fixed-scale approach using anisotropic lattices. Here we present the status of these studies, including ...

    • Quark-gluon plasma phenomenology from the lattice 

      RYAN, SINEAD (2014)
      The FASTSUM Collaboration has calculated several quantities relevant for QCD studies at non-zero temperature using the lattice technique. We report here our results for the (i) interquark potential in charmonium; (ii) ...

    • Quark-Gluon Plasma: From lattice simulations to experimental results 

      RYAN, SINEAD (2014)
      Theoretical studies of quarkonia can elucidate some of the important properties of the quark–gluon plasma, the state of matter realised when the temperature exceeds O (150) MeV, currently probed by heavy-ion collisions ...

    • Quenched QCD with O(a) improvement: The spectrum of light hadrons 

      RYAN, SINEAD MARIE (American Physical Society, 2000)
      We present a comprehensive study of the masses of pseudoscalar and vector mesons, as well as octet and decuplet baryons computed in O(a)-improved quenched lattice QCD. Results have been obtained using the nonperturbative ...

    • Quillen homology for operads via Gr?bner bases 

      Dotsenko, Vladimir (2013)
      The main goal of this paper is to present a way to compute Quillen homology of operads. The key idea is to use the notion of a shuffle operad we introduced earlier; this allows to compute, for a symmetric operad, the ...

    • R**4 corrections to conifolds and G(2)-holonomy spaces 

      FROLOV, SERGEY (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 

      FROLOV, SERGEY (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 

      Ryan, Sinead; Peardon, Michael (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 

      McGurk, Brian (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 

      Pluta, Robert (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 ...

    • Reduction of Five-Dimensional Uniformly Levi Degenerate CR Structures to Absolute Parallelisms 

      ZAITSEV, DMITRI (2013)

    • Remarks on the rigidity of CR-manifolds 

      ZAITSEV, DMITRI (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 

      FROLOV, SERGEY (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 

      MacMaghnusa, Darran (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 ...

    • Rigidity of CR maps between Shilov boundaries of bounded symmetric domains 

      ZAITSEV, DMITRI (2013)

    • Robust layer-resolving methods for various Prandtl problems 

      Butler, John (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 

      FROLOV, SERGEY (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 ...
