  • Water waves and Integrability 

    IVANOV, ROSSEN (Royal Society, 2007)
    The Euler?s equations describe the motion of inviscid fluid. In the case of shallow water, when a perturbative asymtotic expansion of the Euler?s equations is taken (to a certain order of smallness of the scale parameters), ...

  • Weak*-continuity of Jordan triple products and its applications 

    TIMONEY, RICHARD (Institut for Matematiske Fag, Aarhus Universitet, 1986)

  • Weyl's theorem and tensor products: a counterexample. 

    KITSON, DEREK (Elsevier, 2011)
    Approximately fifty percent of Weyl's theorem fails to transfer from Hilbert space operators to their tensor product. As a biproduct we find that the product of circles in the complex plane is a limacon.

  • The worldsheet low-energy limit of the AdS_4 x CP^3 superstring 

    BYKOV, DMITRI (Elsevier, 2010)
    We consider the AdS_4 x CP^3 superstring sigma-model in the background of the ?spinning string? classical solution, which possesses two Noether spins. In the limit when one of the spins is infinite there are massless ...

  • Yang-Baxter integrable open quantum systems 

    Paletta, Chiara (Trinity College Dublin. School of Mathematics. Discipline of Pure & Applied Mathematics, 2023)
    The main result of this thesis is the use of the boost operator to develop a systematic method to construct new integrable spin chains with nearest-neighbour interaction and characterized by an R-matrix of non-difference ...

  • Yang-Mills instantons on the taub-NUT space and supersymmetric N=2 gauge theories with impurities 

    O'Hara, Clare (Trinity College (Dublin, Ireland). School of Mathematics, 2010)
    We write a formula for arbitrary charge calorons, instantons on R3 x S1, in terms of the Green's function of the Laplacian defined for the Nahm Transform, thus generalising the formula for the charge one caloron derived ...

  • The Zamolodchikov-Faddeev Algebra for AdS_5 x S^5 Superstring 

    FROLOV, SERGEY (2007)
    We discuss the Zamolodchikov-Faddeev algebra for the superstring sigmamodel on AdS5 ? S5. We find the canonical su(2|2)2 invariant S-matrix satisfying the standard Yang-Baxter and crossing symmetry equations. Its ...

  • A zero-mode quantization of the Skyrmion 

    HOUGHTON, CONOR JAMES (Elsevier, 2006)
    In the semi-classical approach to the Skyrme model, nuclei are approximated by quantum mechanical states on a finite-dimensional space of field configurations; in zero-mode quantization this space is generated by rotations ...
