  • Recursion operators of some equations of hydrodynamic type 

    Gurses, M.; Zheltukhin, K. (American Institute of Physics, 2001-03)
    We give a general method for constructing recursion operators for some equations of hydrodynamic type, admitting a nonstandard Lax representation. We give several examples for N = 2 and N = 3 containing the equations of ...
  • Borel-Smith functions and the Dade Group

    We show that there is an exact sequence of biset functors over p-groups0 → Cb over(→, j) B* over(→, Ψ) DΩ → 0 where Cb is the biset functor for the group of Borel-Smith functions, B* is the dual of the Burnside ring functor, ...
  • Computer experiments to determine whether over- or under-counting necessarily affects the determination of difference in cell number between experimental groups 

    Heller, B.; Schweingruber, F.; Guvenc, D.; Heller, A. (Elsevier, 2001-03-30)
    Computer cell counting experiments were performed in order to examine the consequences of over- or under-counting. The three-dimensional reaggregate culture laboratory environment for cell counting was used as a model for ...
  • On Smoothness of the Green Function for the Complement of a Rerefied Cantor-Type Set 

    Altun, M.; Goncharov, A. (Springer Verlag, 2011)
    Smoothness of the Green functions for the complement of rarefied Cantor-type sets is described in terms of the function Φ(δ)=(1/log 1/δ) that gives the logarithmic measure of sets. Markov's constants of the corresponding ...
  • On contractibility of th orbit space of a G-poset of Brauer pairs 

    Barker, L. (Elsevier, 1999-02-15)
    Given ap-blockbof a finite groupG, we show that theG-poset of Brauer pairs strictly containing (1,b) has contractibleG-orbit space. A similar result is proved for certainG-posets ofp-subgroups. Both results generalise P. ...
  • The dual of the principal ideal generated by a pure p-form 

    Dibag, I. (Elsevier, 2002-06-01)
    We observe that our methods in [J. Algebra 183 (1996) 24-37] generalize to determine the dual (e.g. annihilator) of the principal ideal generated by a pure p-form. © 2002 Elsevier Science (USA). All rights reserved.

    Kerimov, A. (American Institute of Physics, 1999-10)
    Uniqueness of Gibbs states in the one-dimensional antiferromagnetic model with very long-range interaction is established. © 1999 American Institute of Physics.
  • Backlund transformations for discrete Painleve equations: Discrete P-II-P-V 

    Sakka, A.; Mugan, U. (Elsevier, 2006)
    Transformation properties of discrete Painleve´ equations are investigated by using an algorithmic method. This method yields explicit transformations which relates the solutions of discrete Painleve´ equations, discrete ...
  • Essential cohomology for elementary abelian p-groups 

    Altunbulak Aksu, F.; Green, D. J. (Elsevier, 2009-12)
    For an odd prime p the cohomology ring of an elementary abelian p-group is polynomial tensor exterior. We show that the ideal of essential classes is the Steenrod closure of the class generating the top exterior power. As ...
  • On the classification of Darboux integrable chains 

    Habibullin, I.; Zheltukhina, N.; Pekcan, A. (American Institute of Physics, 2008)
    We study differential-difference equation (d/dx) t (n+1,x) =f (t (n,x),t (n+1,x), (d/dx) t (n,x)) with unknown t (n,x) depending on continuous and discrete variables x and n. Equation of such kind is called Darboux integrable, ...

    Tudor, T.; Gheondea, A. (Optical Society of America, 2007)
    A unified treatment of the Pauli algebraic forms of the linear operators defined on a unitary linear space of two dimensions over the field of complex numbers C1 is given. The Pauli expansions of the normal and nonnormal ...
  • Easily monitored entagled state 

    Can, M. A.; Klyachko, A.; Shumovsky, A. (American Institute of Physics, 2002-12-23)
    We discuss the generation and monitoring of durable atomic entangled state via Raman-type process, which can be used in the quantum information processing. (C) 2002 American Institute Of Physics.
  • Carleson Measures for Besov Spaces on the Ball with Applications 

    Kaptanoglu, H. T. (Elsevier, 2007-09-15)
    Carleson and vanishing Carleson measures for Besov spaces on the unit ball of CN are characterized in terms of Berezin transforms and Bergman-metric balls. The measures are defined via natural imbeddings of Besov spaces ...

    Pakianathan, J.; Yalcin, E. (Elsevier, 2012-05-01)
    A central extension of the form E: 0 → V→ G→ W→ 0, where V and W are elementary abelian 2-groups, is called Bockstein closed if the components qi∈H *(W,F 2) of the extension class of E generate an ideal which is closed ...
  • On Nilpotent ideals in the cohomology ring of a finite group 

    Pakianathan, J.; Yalcin, E. (Elsevier, 2003-09)
    In this paper we "nd upper bounds for the nilpotency degree of some ideals in the cohomology ring of a "nite group by studying "xed point free actions of the group on suitable spaces. The ideals we study are the kernels ...
  • Quantum and classical integrable sine-Gordon model with defect 

    Habibulin, I.; Kundu, A. (Elsevier, 2008-06-01)
    Defects which are predominant in a realistic model, usually spoil its integrability or solvability. We on the other hand show the exact integrability of a known sine-Gordon field model with a defect (DSG), at the classical ...

    Gurses, M.; Tek, S. (Elsevier, 2014-01)
    We consider 2-surfaces arising from the Korteweg-de Vries (KdV) hierarchy and the KdV equation. The surfaces corresponding to the KdV equation are in a three-dimensional Minkowski (M3) space. They contain a family of ...
