  • Foliations of codimension one and Milnor's conjecture 
    Bolotov, D.V. (Журнал математической физики, анализа, геометрии, 2018)
    We prove that a fundamental group of leaves of a codimension one C²- foliation with nonnegative Ricci curvature on a closed Riemannian manifold is finitely generated and almost Abelian, i.e., it contains finitely generated ...
  • Lagrange Stability of Semilinear Differential-Algebraic Equations and Application to Nonlinear Electrical Circuits 
    Filipkovska, M.S. (Журнал математической физики, анализа, геометрии, 2018)
    A semilinear differential-algebraic equation (DAE) is studied focusing on the Lagrange stability (instability). The conditions for the existence and uniqueness of global solutions (a solution exists on an infinite interval) ...
  • Non-Differentiable Functions Defined in Terms of Classical Representations of Real Numbers 
    Serbenyuk, S.O. (Журнал математической физики, анализа, геометрии, 2018)
    The present paper is devoted to the functions from a certain subclass of non-differentiable functions. The arguments and values of the considered functions are represented by the s-adic representation or the nega-s-adic ...
  • Nonlinear Dynamics of Solitons for the Vector Modified Korteweg-de Vries Equation 
    Fenchenko, V.; Khruslov, E. (Журнал математической физики, анализа, геометрии, 2018)
    The vector generalization of the modified Korteweg–de Vries equation is considered and the inverse scattering transform for solving this equation is developed. The solitons and the breather solutions are constructed and ...
  • Ricci Solitons on Lorentzian Four-Dimensional Generalized Symmetric Spaces 
    Bouharis, A.; Djebbar, B. (Журнал математической физики, анализа, геометрии, 2018)
    The existence of non-trivial, i.e., non-Einstein, Ricci solitons on fourdimensional Lorentzian generalized symmetric spaces is proved. Moreover, it is shown that only steady Ricci solitons can be gradient.
  • Surfaces of Revolution with Vanishing Curvature in Galilean 3-Space 
    Dede, M.; Ekici, C.; Goemans, W. (Журнал математической физики, анализа, геометрии, 2018)
    In the paper, three types of surfaces of revolution in the Galilean 3- space are defined and studied. The construction of the well-known surface of revolution, defined as the trace of a planar curve rotated about an axis ...
  • The Solvability of the Initial-Boundary Value Problems for a Nonlinear Schrödinger Equation with a Special Gradient Term 
    Yagub, G.; Ibrahimov, N.S.; Zengin, M. (Журнал математической физики, анализа, геометрии, 2018)
    In this paper, the initial-boundary value problems for the two-dimensional nonlinear Schrödinger equation with a special gradient term with purely imaginary coefficients in the nonlinear part, when the coefficients of the ...
