An O(a) modified lattice setup of the Schrödinger functional in SU(3) gauge theory
(2011)The setup of the QCD Schrödinger functional (SF) on the lattice with staggered quarks requires an even number of points L/a in the spatial directions, while the Euclidean time extent of the lattice, T/a, must be odd. ...

Obstructions to embeddability into hyperquadrics and explicit examples
(Springer, 2008)We give series of explicit examples of Levinondegenerate realanalytic hypersurfaces in complex spaces that are not transversally holomorphically embeddable into hyperquadrics of any dimension. For this, we construct ... 
Octahedral and dodecahedral monopoles
(IOP, 1996)It is shown that there exists a charge five monopole with octahedral symmetry and a charge seven monopole with icosahedral symmetry. A numerical implementation of the ADHMN construction is used to calculate the energy ... 
The Offshell Symmetry Algebra of the Lightcone AdS(5) x S**5 Superstring
(Institute of Physics, 2007)We analyse the psu(2, 24) supersymmetry algebra of a superstring propagating in the AdS5 ? S5 background in the uniform lightcone gauge. We consider the offshell theory by relaxing the levelmatching condition and ... 
On a problem of H. Bohr
(Societe Royale des Sciences de Liege, 1991) 
On AdS(5) x S**5 String Smatrix.
(Elsevier, 2006)Recently two interesting conjectures about the string Smatrix on AdS5?S5 have been made. First, assuming the existence of a Hopf algebra symmetry Janik derived a functional equation for the dressing factor of the quantum ... 
On Hamiltonian structure of the spin RuijsenaarsSchneider model
(Institute of Physics, 1998)The Hamiltonian structure of spin generalization of the rational RuijsenaarsSchneider model is found by using the Hamiltonian reduction technique. It is shown that the model possesses the current algebra symmetry. The ... 
On Leviflat hypersurfaces with prescribed boundary
(2010)We address the problem of existence and uniqueness of a Leviflat hypersurface M in ?n with prescribed compact boundary S for n ? 3. The situation for n ? 3 differs sharply from the well studied case n = 2. We first establish ... 
On local CRtransformation of Levidegenerate group orbits in compact Hermitian symmetric spaces
(European Mathematical Society, 2006) 
On Lorentz invariance and supersymmetry of four particle scattering amplitudes in S(N) R**8 orbifold sigma model
(American Physical Society, 1999)The SNR8 supersymmetric orbifold sigma model is expected to describe the Infrared limit of the matrix string theory. In the framework of the model the type IIA string interaction is governed by a vertex which was recently ... 
On oneloop correction to energy of spinning strings in S(5)
(American Physical Society, 2005)We revisit the computation of the 1loop AdS5?S5 superstring sigma model correction to the energy of a closed circular string rotating in S5. The string is spinning around its center of mass with two equal angular momenta ... 
On String Smatrix, Bound States and TBA
(2007)The study of finite J effects for the lightcone AdS5 ? S5 superstring by means of the Thermodynamic Bethe Ansatz requires an understanding of a companion 2d theory which we call the mirror model. It is obtained from the ... 
On symmetric CauchyRiemann manifolds
(Elsevier, 2000)The Riemannian symmetric spaces play an important role in different branches of mathematics. By definition, a (connected) Riemannian manifold M is called symmetric if, to every a ? M, there exists an involutory isometric ... 
On the automorphism groups of algebraic bounded domains
(Springer, 1995) 
On the central Haagerup tensor product and completely bounded mappings of a C*algebra,
(2005)We consider the natural contractive map from the central Haagerup tensor product of a unital C*algebra A with itself to the space of completely bounded maps CB ( A ) on A. We establish the necessity of the known sufficient ... 
On the constraints defining BPS monopoles
(Springer Science and Business Media, 2000)We discuss the explicit formulation of the transcendental constraints defining spectral curves of SU.2/ BPS monopoles in the twistor approach of Hitchin, following Ercolani and Sinha. We obtain an improved version of the ... 
On the correspondence between gravity fields and CFT operators
(2000)It is shown that a nonlinear derivativedependent transformation of gravity fields changes correlation functions in a boundary CFT, and, therefore, corresponds to a change of a basis of operators in the CFT. It is argued ... 
On the origin of supergravity boundary terms in the AdS/CFT correspondence
(Elsevier, 1999)The standard formulation of the AdS/CFT correspondence is incomplete since it requires adding to a supergravity action some a priori unknown boundary terms. We suggest a modification of the correspondence principle based ...
