  • Virasoro amplitude from the S(N) R**24 orbifold sigma model 

    FROLOV, SERGEY (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 ...
  • 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 ...
  • 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 ...
