  • Algebraic dependences of meromorphic mappings in several complex variables 
    Duc Thoan Pham; Viet Duc Pham (Український математичний журнал, 2010)
    We give some theorems on algebraic dependence of meromorphic mappings in several complex variables into complex projective spaces.
  • Are the degrees of the best (co)convex and unconstrained polynomial approximations the same? II 
    Korotun, K.; Leviatan, D.; Shevchuk, I.A. (Український математичний журнал, 2010)
  • A -деформації поверхні зі стаціонарною довжиною LGT-ліній 
    Безкоровайна, Л.Л.; Вашпанова, Т.Ю. (Український математичний журнал, 2010)
    Объектом исследования в работе являются бесконечно малые ареальиые деформации (A-деформации) первого порядка, при которых сохраняются длины LGT-линий поверхности в E₃ - пространстве. Доказано, что любая регулярная поверхность ...
  • Best approximation by ridge functions in Lp-spaces 
    Maiorov, V.E. (Український математичний журнал, 2010)
  • Characterization of A₁₆ by a noncommuting graph 
    Davoudi Monfared, М.; Darafsheh, M.R. (Український математичний журнал, 2010)
    Let G be a finite non-Abelian group. We define a graph Γ G ; called the noncommuting graph of G; with a vertex set G − Z(G) such that two vertices x and y are adjacent if and only if xy ≠ yx: Abdollahi, Akbari, and Maimani ...
  • Common fixed points and invariant approximation of R-subweakly commuting maps in convex metric spaces 
    Narang, T.D.; Chandok, S. (Український математичний журнал, 2010)
    Sufficient conditions for the existence of a common fixed point of R-subweakly commuting mappings are established within the framework of a convex metric space. As applications, we obtain various results on the best ...
  • Completeness of invariant ideals in groups 
    Banakh, T.; Lyakovska, N. (Український математичний журнал, 2010)
    We introduce and study various notions of completeness of translation-invariant ideals in groups.
  • Deformations of circle-valued Morse functions on surfaces 
    Maksymenko, S.I. (Український математичний журнал, 2010)
    Let M be a smooth connected orientable compact surface and let Fcov(M,S1) be a space of all Morse functions f : M → S₁ without critical points on ∂M such that, for any connected component V of ∂M, the restriction f : V → ...
  • Elements of a non-Gaussian analysis on the spaces of functions of infinitely many variables 
    Kachanovsky, N.A. (Український математичний журнал, 2010)
    We present a review of some results of the non-Gaussian analysis in the biorthogonal approach and consider elements of the analysis associated with the generalized Meixner measure. The main objects of our interest are ...
  • Estimation of a distribution function by an indirect sample 
    Babilua, P.; Nadaraya, E.; Sokhadze, G. (Український математичний журнал, 2010)
    The problem of estimation of a distribution function is considered in the case where the observer has access only to a part of the indicator random values. Some basic asymptotic properties of the constructed estimates are ...
  • General algorithm of computation of c-table and detection of valleys 
    Gilewicz, J.; Pindor, M. (Український математичний журнал, 2010)
    We present a review of all interesting results concerning the c-table obtained by the authors for the last two decades. These results are not widely known because they were presented in publications of limited circulation. ...
  • Kernel of a map of a shift along the orbits of continuous flows 
    Maksymenko, S.I. (Український математичний журнал, 2010)
    Let F:M × R → M be a continuous flow on a topological manifold M. For every subset V⊂M, we denote by P(V) the set of all continuous functions ξ:V→R such that F(x,ξ(x))=x for all x∈V. These functions vanish at nonperiodic ...
  • On a continued fraction of order twelve 
    Vasuki, K.R.; Abdulrawf, A.A. Kahtan; Sathish Kumar, C. (Український математичний журнал, 2010)
    We present some new relations between a continued fraction U(q) of order 12 (established by M. S. M. Naika et al.) and U(q n) for n = 7, 9, 11, 13.
  • On generalization of ⊕-cofinitely supplemented modules 
    Nisanci, B.; Pancar, A. (Український математичний журнал, 2010)
    We study the properties of ⊕-cofinitely radical supplemented modules, or, briefly, cgs ⊕-modules. It is shown that a module with summand sum property (SSP) is cgs ⊕ if and only if M/w Loc⊕ M (w Loc⊕ M is the sum of all ...
  • On impulsive Sturm–Liouville operators with Coulomb potential and spectral parameter linearly contained in boundary conditions 
    Amirov, R. Kh.; Topsakal, N.; Guldu, Y. (Український математичний журнал, 2010)
    The Sturm–Liouville problem with linear discontinuities is investigated in the case where an eigenparameter appears not only in a differential equation but also in boundary conditions. Properties and the asymptotic behavior ...
  • On singularities of the Galilean spherical darboux ruled surface of a space curve in G₃ 
    Sahin, T.; Yilmaz, M. (Український математичний журнал, 2010)
    We study the singularities of Galilean height functions intrinsically related to the Frenet frame along a curve embedded into the Galilean space. We establish the relationships between the singularities of the discriminant ...
  • On the asymptotic extension dimension 
    Repovs, D.; Zarichnyi, М. (Український математичний журнал, 2010)
    We introduce an asymptotic counterpart of the extension dimension defined by Dranishnikov. The main result establishes the relationship between the asymptotic extensional dimension of a proper metric space and the extension ...
  • On the convergence of positive increasing functions to infinity 
    Buldygin, V.V.; Klesov, O.I.; Steinebach, J.G. (Український математичний журнал, 2010)
    We study the conditions of convergence to infinity for some classes of functions extending the well-known class of regularly varying (RV) functions, such as, e.g., O-regularly varying (ORV) functions or positive increasing ...
  • On the lattice oscillator-type Kirkwood–Salsburg equation with attractive many-body potentials 
    Skrypnik, W.I. (Український математичний журнал, 2010)
    We consider a lattice oscillator-type Kirkwood–Salsburg (KS) equation with general one-body phase measurable space and many-body interaction potentials. For special choices of the measurable space, its solutions describe ...
  • On the maximal operator of (C, α)-means of Walsh–Kaczmarz–Fourier series 
    Goginava, U.; Nagy, K. (Український математичний журнал, 2010)
    Simon [J. Approxim. Theory, 127, 39–60 (2004)] proved that the maximal operator σα,κ,* of the (C, α)-means of the Walsh–Kaczmarz–Fourier series is bounded from the martingale Hardy space H p to the space L p for p > 1 / ...
