  • Tomkinson, M.J. (Український математичний журнал, 1991)
    A splitting Theorem for FC-hypercentral group G and ZG-module of finite rank is obtained. According to this Theorem, under certain conditions, every extention E of the ZG-module A by the group G is split and all the ...
  • 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 ...
  • Kangkang Wang (Український математичний журнал, 2011)
    We study strong limit theorems for a bivariate function sequence of an nonhomogeneous Markov chain indexed by a generalized Bethe tree on a generalized random selection system by constructing a nonnegative martingale. As ...
  • Razani, A.; Parvaneh, V.; Abbas, M. (Український математичний журнал, 2011)
    We extend the common fixed point theorem established by Zhang and Song in 2009 to generalized (ψ, φ)f,g weak contractions. Moreover, we give an example that illustrates the main result. Finally, some common fixed point ...
  • Zong, Z.J. (Український математичний журнал, 2012)
    We study backward stochastic differential equations (BSDE) under weak assumptions on the data. We obtain a comonotonic theorem for BSDE in Lp; 1 < p ≤ 2: As applications of this theorem, we study the relation between Choquet ...
  • Alomari, M.W. (Український математичний журнал, 2012)
    Some analogs of Dragomir’s generalization of the Ostrowski integral inequality are established. Some sharp inequalities are proved. An application to the composite quadrature rule is provided.
  • Hong-Bing Qiu; Ji Luo; Jiajia Zhang (Український математичний журнал, 2015)
    There are some discussions concerning the admissibility of estimated regression coefficients under the balanced loss function in the general linear model. We study this issue for the generalized linear regression model. ...
  • Elworthy, K.D.; Zhi-Ming Ma (Український математичний журнал, 1997)
    A variation on the notion of “admissibility” for vector fields on certain infinite-dimensional manifolds with measures on them is described. It leads to the construction of associated diffusions and Markov semigroups on ...
  • Hale, J.K. (2007)
    За допомогою спостережуваних величин та змінної стану динамічного процесу визначено загальне еволюційне рівняння, що узагальнює класичні звичайні диференціальні рівняння, диференціальні рівняння з частинними похідними та ...
  • Albeverio, S.; Berezansky, Yu.M.; Tesko, V.A. (Український математичний журнал, 2007)
    We propose a generalization of an extended stochastic integral in the case of integration with respect to a wide class of random processes. In particular, we obtain conditions for the coincidence of the considered ...
  • 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, ...
  • Rassias, J.M.; Xu, T.Z.; Xu, W.X. (Український математичний журнал, 2011)
    We determine the general solution of the functional equation f(x+ky)+f(x−ky) = g(x+y)+g(x−y)+ +h(x)+h˜(y) for fixed integers k with k 6= 0, ±1 without assuming any regularity condition on the unknown functions f, g, h, ...
  • Zhou, W. (Український математичний журнал, 2015)
    We present a hybrid HS- and PRP-type conjugate gradient method for smooth optimization that converges globally and R-linearly for general functions. We also introduce its inexact version for problems of this kind in which ...
  • Cheng, C.-L.; Kukush, A.G. (Український математичний журнал, 2004)
    Polynomial regression models with errors in variables are considered. A goodness-of-fit test is constructed, which is based on an adjusted least-squares estimator and modifies the test introduced by Zhu et al. for a linear ...
  • Nguyen Doan Tuan (Український математичний журнал, 2004)
    We prove a generalization of the Brody reparametrization lemma.
  • 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.
  • Zhu Zhanmin (Український математичний журнал, 2013)
    A ring R is called right almost MGP-injective (or AMGP-injective) if, for any 0 ≠ a ∈ R, there exists an element b ∈ R such that ab = ba ≠ 0 and any right R-monomorphism from abR to R can be extended to an endomorphism of ...
  • Fima, P.; Vainerman, L. (Український математичний журнал, 2008)
    We construct a one parameter deformation of the group of 2×2 upper triangular matrices with determinant 1 using the twisting construction. An interesting feature of this new example of a locally compact quantum group is ...
  • Petrina, D.Ya.; Caraffini, G.L. (Український математичний журнал, 2005)
    Dynamics of a system of hard spheres with inelastic collisions is investigated. This system is a model for granular flow. The map induced by a shift along the trajectory does not preserve the volume of the phase space, and ...
  • Bor, H. (Український математичний журнал, 2012)
    We prove a theorem on ∣ N¯,pn,θn ∣k-summability by using a new general class of power increasing sequences instead of a quasi-η-power increasing sequence. This theorem also includes some new and known results.
