Konishi operator at intermediate coupling.
(2011)TBA equations for twoparticle states from the sl(2) sector proposed by Arutyunov, Suzuki and the author are solved numerically for the Konishi operator descendent up to 't Hooft's coupling 2046. The data obtained ... 
Krylov subspaces from bilinear representations of nonlinear systems
(Emerald, 2007)For efficient simulation of stateoftheart dynamical systems as arise in all aspects of engineering, the development of reducedorder models is of paramount importance. While linear reduction techniques have received ... 
Large scale parallel network simulation
(Trinity College (Dublin, Ireland). School of Mathematics, 2004)Simulation is one of the primary tools used in studying computer networks. However the difficulties of simulating a network grow with its size. With the hardware resources currently available it is not feasible to simulate ... 
Lattice determinations of the strange quark mass
(University of Chicago, 1999)The importance of the strange quark mass, as a fundamental parameter of the Standard Model (SM) and as an input to many interesting quantities, has been highlighted in many reviews, eg in Ref . A first principles calculation ... 
Lattice QCD calculation of antiB > D lepton antineutrino decay formfactors at zero recoil
(20081009)A lattice QCD calculation of the B? ?Dl?? decay form factors is presented. We obtain the value of the form factor h+(w) at the zerorecoil limit w=1 with high precision by considering a ratio of correlation functions in ... 
Lax pair for strings in LuninMaldacena background.
(2005)Recently Lunin andMaldacena used an SL(3,R) transformation of the AdS5?S5 background to generate a supergravity solution dual to a socalled deformation of N = 4 super YangMills theory. We use a TdualityshiftTduality ... 
Lie group structures on automorphism groups of realanalytic CR manifolds
(The Johns Hopkins University Press, 2008)Given any realanalytic CR manifold M, we provide general conditions on M guar anteeing that the group of all its global realanalytic CR automorphisms AutCR(M) is a Lie group (in an appropriate topology). In particular, ... 
Logarithmic asymptotics in Queueing Theory and Risk Theory
(Trinity College (Dublin, Ireland). School of Mathematics, 2000)This thesis addresses four distinct, but related, problems. All four involve large deviation theory. The first problem is to relate the logarithmic asymptotics of the single server queue length distribution to the long ... 
Logarithmic corrections to higher twist scaling at strong coupling from AdS/CFT.
(Elsevier, 2007)We compute 1loop correction E1 to the energy of folded string in AdS5?S5 (carrying spin S in AdS5 and momentum J in S5) using a ?long string? approximation in which Smuch greaterthanJmuch greaterthan1. According to the ... 
Matrix models, quantum gravity and the spectral dimension
(Proceedings of Science, 2005)Monte Carlo studies on nonperturbative 2D Euclidean Quantum Gravity can be done with the use of the Dynamical Triangulations method. The Monte Carlo moves defined within the dynamical triangulation method can be encompassed ... 
Measuring the aspect ratio renormalization of anisotropiclattice gluons
(American Physical Society, 2001)Using tadpoleimproved actions we investigate the consistency between different methods of measuring the aspect ratio renormalization of anisotropiclattice gluons for bare aspect ratios x054,6,10 and inverse lattice spacing ... 
Melting of P wave bottomonium states in the quarkgluon plasma from lattice NRQCD
(2013)We study the fate of P wave bottomonium states in the quarkgluon plasma, using a spectral function analysis of euclidean lattice cor relators. The correlators are obtained from lattice QCD simulations with two ... 
Mesons at high temperature in Nf=2 QCD
(American Physical Society, 2006)We report first results for spectral functions of charmonium in 2flavour QCD. The spectral functions are determined from vector and pseudoscalar correlators on a dynamical, anisotropic lattice. J/ and c are found ... 
Methods for calculating option prices with earlyexercise features
(Trinity College (Dublin, Ireland). School of Mathematics, 2006)In this dissertation we deal with two distinct methods for pricing financial options with earlyexercise features. First we use finite difference methods to calculate the prices, examining in particular two new schemes ... 
Methods of ascent and descent in multivariable spectral theory
(Trinity College (Dublin, Ireland). School of Mathematics, 2009)In this dissertation the theory of ascent and descent for a linear operator acting on a vector space is extended to arbitrary sets of operators and applied to the study of joint spectra for finite commuting systems of bounded ...
