  • A class of p-valent meromorphic functions defined by the Liu–Srivastava operator 
    Seoudy, T.M.; Aouf, M.K. (Український математичний журнал, 2014)
    We introduce a subclass of p-valent meromorphic functions involving the Lui–Srivastava operator and investigate various properties of this subclass. We also indicate the relationships between various results presented in ...
  • A generalization of lifting modules 
    Kalati, T.A. (Український математичний журнал, 2014)
    We introduce the notion of I -lifting modules as a proper generalization of the notion of lifting modules and present some properties of this class of modules. It is shown that if M is an I -lifting direct projective module, ...
  • Anisotropic differential operators with parameters and applications 
    Shakhmurov, V.B. (Український математичний журнал, 2014)
    In the paper, we study the boundary-value problems for parameter-dependent anisotropic differential-operator equations with variable coefficients. Several conditions for the uniform separability and Fredholmness in ...
  • Asymptotic solutions of the Dirichlet problem for the heat equation at a characteristic point 
    Antoniouk, A.V.; Kiselev, O.M.; Tarkhanov, N.N. (Український математичний журнал, 2014)
    The Dirichlet problem for the heat equation in a bounded domain G⊂Rn+1 is characteristic because there are boundary points at which the boundary touches a characteristic hyperplane t=c, where c is a constant. For the first ...
  • Atoms in the p-localization of stable homotopy category 
    Drozd, Yu.A.; Kolesnyk, P.O. (Український математичний журнал, 2014)
    We study p-localizations, where p is an odd prime, of the full subcategories Sⁿ of stable homotopy category formed by CW-complexes with cells in n successive dimensions. Using the technique of triangulated categories and ...
  • Big Picard theorem for meromorphic mappings with moving hyperplanes in Pn(C) 
    Quang, Si Duc; Giang, Ha Huong (Український математичний журнал, 2014)
    We present some extension theorems in the style of the Big Picard theorem for meromorphic mappings of Cm into Pn(C) with a few moving hyperplanes.
  • Classification of the regular components of two-dimentional inner maps 
    Vlasenko, I.Yu. (Український математичний журнал, 2014)
    We propose a topological classification of dynamical systems generated by two-dimensional inner maps on the fully invariant regular components of a wandering set with special attracting boundary (to within the topological ...
  • CLT-groups with Hall S-quasinormally embedded subgroups 
    Jianjun Liu; Shirong Li (Український математичний журнал, 2014)
    A subgroup H of a finite group G is said to be Hall S-quasinormally embedded in G if H is a Hall subgroup of the S-quasinormal closure H SQG . We study finite groups G containing a Hall S-quasinormally embedded subgroup ...
  • Common fixed-point theorems for nonlinear weakly contractive mappings 
    Chandok, S.; Khan, M.S.; Abbas, M. (Український математичний журнал, 2014)
    Some common fixed-point results for mappings satisfying a nonlinear weak contraction condition within the framework of ordered metric spaces are obtained. The accumulated results generalize and extend several comparable ...
  • Critical points approaches to elliptic problems driven by a p(x)-Laplacian 
    Heidarkhani, S.; Ge, B. (Український математичний журнал, 2014)
    We establish the existence of at least three solutions for elliptic problems driven by a p(x)-Laplacian. The existence of at least one nontrivial solution is also proved. The approaches are based on the variational methods ...
  • Decomposition of directed graphs and the Turán problem 
    Novikov, B.V.; Polyakova, L.Yu.; Zholtkevich, G.N. (Український математичний журнал, 2014)
    We consider vertex decompositions of (di)graphs appearing in the automata theory and establish some properties of these decompositions. These decompositions are applied to the problem of forbidden subgraphs.
  • Fixed point theorems for multivalued generalized nonlinear contractive maps in partial metric spaces 
    Aghajani, A.; Allahyari, K. (Український математичний журнал, 2014)
    We prove some fixed-point results for multivalued generalized nonlinear contractive mappings in partial metric spaces, which generalize and improve the corresponding recent fixed-point results due to Ćirić [L. B. Ćirić, ...
  • Fractional calculus of a unified Mittag-Leffler function 
    Prajapati, J.C.; Nathwani, B.V. (Український математичний журнал, 2014)
    The main aim of the paper is to introduce an operator in the space of Lebesgue measurable real or complex functions L(a, b). Some properties of the Riemann–Liouville fractional integrals and differential operators associated ...
  • Functions and vector fields on C(CPⁿ) -singular manifolds 
    Libardi Alice Kimie Miwa; Sharko, V. (Український математичний журнал, 2014)
  • Generalized Bombieri–Lagarias’ theorem and generalized Li’s criterion with its arithmetic interpretation 
    Sekatski, S.K. (Український математичний журнал, 2014)
    We show that Li’s criterion equivalent to the Riemann hypothesis, i.e., the statement that the sums kn=Σρ(1−(1−1ρ)n) over zeros of the Riemann xi-function and the derivatives are nonnegative if and only if the Riemann ...
  • Generalized semicommutative and skew Armendariz ideals 
    Nikmehr, M.J. (Український математичний журнал, 2014)
    We generalize the concepts of semicommutative, skew Armendariz, Abelian, reduced, and symmetric left ideals and study the relationships between these concepts.
  • Generalized twisted Kloosterman sum over ℤ[i] 
    Varbanets, S. (Український математичний журнал, 2014)
    The twisted Kloosterman sums over Z were studied by V. Bykovsky, A.Vinogradov, N. Kuznetsov, R. W. Bruggeman, R. J. Miatello, I. Pacharoni, A. Knightly, and C. Li. In our paper, we obtain similar estimates for K χ (α, β; ...
  • Groups with the same prime graph as the simple group Dn(5) 
    Babai, A.; Khosravi, B. (Український математичний журнал, 2014)
    Let G be a finite group. The prime graph of G is denoted by Γ(G). Let G be a finite group such that Γ(G)=Γ(Dn(5)), where n≥6. In the paper, as the main result, we show that if n is odd, then G is recognizable by the prime ...
  • I−n-Coherent rings, I−n-semihereditary rings, and I-regular rings 
    Zhanmin, Zhu (Український математичний журнал, 2014)
    Let R be a ring, let I be an ideal of R, and let n be a fixed positive integer. We define and study I−n-injective modules and I−n-flat modules. Moreover, we define and study left I−n-coherent rings, left I−n-semihereditary ...
  • Inequalities for eigenvalues of a system of higher-order differential equations 
    Sun, H.J. (Український математичний журнал, 2014)
    We establish some sharper inequalities for eigenvalues of a system of higher-order differential equations. Moreover, we present some sharper estimates for the upper bound of the (k +1)th eigenvalue and the gaps of its ...
