  • Global Weak Solutions for the Weakly Dissipative μ-Hunter–Saxton Equation 
    Liu, J. (Український математичний журнал, 2013)
    The paper deals with the global existence of weak solutions for a weakly dissipative μ-Hunter–Saxton equation. The problem is analyzed by using smooth data approximating the initial data and Helly’s theorem.
  • Hereditary Properties between a Ring and its Maximal Subrings 
    Azarang, A.; Karamzadeh, O.A.S.; Namazi, A. (Український математичний журнал, 2013)
    We study the existence of maximal subrings and hereditary properties between a ring and its maximal subrings. Some new techniques for establishing the existence of maximal subrings are presented. It is shown that if R is ...
  • Hermite–Hadamard-type inequalities for r-convex functions based on the use of Riemann–Liouville fractional integrals 
    Wang, J.; Deng, J.; Fečkan, M. (Український математичний журнал, 2013)
    By using two fundamental fractional integral identities, we deduce some new Hermite–Hadamard-type inequalities for differentiable r-convex functions and twice-differentiable r-convex functions involving Riemann–Liouville ...
  • Hybrid-type generalized multivalued vector complementarity problems 
    Agarwal, R.P.; Ahmad, M.K.; Salahuddin (Український математичний журнал, 2013)
    We introduce a new type of generalized multivalued vector complementarity problems with moving pointed cone. We discuss the existence results for generalized multivalued vector complementarity problems under inclusive ...
  • Invariant measures for discrete dynamical systems and ergodic properties of generalized Boole-type transformations 
    Блекмор, Д.; Голеня, Й.; Прикарпатський, А.К.; Прикарпатський, Я.А. (Український математичний журнал, 2013)
    Invariant ergodic measures for generalized Boole-type transformations are studied by using an invariant quasimeasure generating function approach based on special solutions for the Frobenius–Perron operator. New two-dimensional ...
  • Locally ϕ-Symmetric Generalized Sasakian-Space Forms 
    Sarkar, A.; Sen, M. (Український математичний журнал, 2013)
    The aim of the present paper is to find necessary and sufficient conditions for locally ϕ-symmetric generalized Sasakian-space forms to have constant scalar curvature, η -parallel Ricci tensor, and cyclic parallel Ricci ...
  • Local Maxima of the Potential Energy on Spheres 
    Radchenko, D.V. (Український математичний журнал, 2013)
  • Lyapunov-type inequalities for quasilinear systems with antiperiodic boundary conditions 
    Youyu Wang; Yannan Li; Yongzhen Bai (Український математичний журнал, 2013)
    We establish some new Lyapunov-type inequalities for one-dimensional p-Laplacian systems with antiperiodic boundary conditions. The lower bounds of eigenvalues are presented.
  • Method of Lines for Quasilinear Functional Differential Equations 
    Czernous, W.; Kamont, Z. (Український математичний журнал, 2013)
    We give a theorem on the estimation of error for approximate solutions to ordinary functional differential equations. The error is estimated by a solution of an initial problem for a nonlinear functional differential ...
  • New Sharp Ostrowski-type Inequalities and Generalized Trapezoid-type Inequalities for Riemann–Stieltjes Integrals and their Applications 
    Alomari, M.W. (Український математичний журнал, 2013)
    We prove new sharp weighted generalizations of Ostrowski-type and generalized trapezoid-type inequalities for Riemann–Stieltjes integrals. Several related inequalities are deduced and investigated. New Simpson-type ...
  • On 3-dimensional f-Kenmotsu manifolds and Ricci solitons 
    Yildiz, A.; De, U.C.; Turan, M. (Український математичний журнал, 2013)
    The aim of the present paper is to study 3-dimensional f-Kenmotsu manifolds and Ricci solitons. First, we give an example of a 3-dimensional f-Kenmotsu manifold. Then we consider a Riccisemisymmetric 3-dimensional f-Kenmotsu ...
  • On equivalent cone metric spaces 
    Ölmez, Ö.; Aytar, S. (Український математичний журнал, 2013)
    We explore the necessary and sufficient conditions for the two cone metrics to be topologically equivalent.
  • On Lie Ideals and Generalized Jordan Left Derivations of Prime Rings 
    Rehman, N.; Ansari, A.Z. (Український математичний журнал, 2013)
    Let R be a prime ring with characteristic different from 2 and U be a Lie ideal of R. In the paper, we initiate the study of generalized Jordan left derivations on Lie ideals of R and prove that every generalized Jordan ...
  • On M-projectively flat LP-Sasakian manifolds 
    Zengin, F.Ö. (Український математичний журнал, 2013)
    In the present paper, we study the nature of LP-Sasakian manifolds admitting the M-projective curvature tensor. It is examined whether this manifold satisfies the condition W(X, Y ).R = 0. Moreover, it is proved that, in ...
  • On polymer expansions for generalized Gibbs lattice systems of oscillators with ternary interaction 
    Skrypnik, W.I. (Український математичний журнал, 2013)
    We propose a new short proof of the convergence of high-temperature polymer expansions in the thermodynamic limit of canonical correlation functions for classical and quantum Gibbs lattice systems of oscillators interacting ...
  • On Some Multidimensional Hilbert-Type Inequalities in the Discrete Case 
    Krnić, M.; Vuković, P. (Український математичний журнал, 2013)
    Motivated by the results of Huang, we deduce a pair of discrete multidimensional Hilbert-type inequalities involving a homogeneous kernel of negative degree. We also establish conditions under which the constant factors ...
  • On Supplement Submodules 
    Nebiyev, C.; Pancar, A. (Український математичний журнал, 2013)
    We investigate some properties of supplement submodules. Some relations between lying-above and weak supplement submodules are also studied. Let V be a supplement of a submodule U in M. Then it is possible to define a ...

    Şenel, M.T. (Український математичний журнал, 2013)
  • On the interaction of an elasticwall with a poiseuille-type flow 
    Chueshov, I.; Ryzhkova, I. (Український математичний журнал, 2013)
    We study the dynamics of a coupled system formed by the 3D Navier–Stokes equations linearized near a certain Poiseuille-type flow in an (unbounded) domain and a classical (possibly nonlinear) equation for transverse ...
  • On the invariants of root subgroups of finite classical groups 
    Jizhu Nan; Yufang Qin (Український математичний журнал, 2013)
    We show that invariant fields Fq(X1, . . . , Xn)G are purely transcendental over Fq if G are root subgroups of finite classical groups. The key step is to find good similar groups of our groups. Moreover, the invariant ...
