  • Parabolic Foliations on Three-Manifolds 
    Krouglov, V. (Журнал математической физики, анализа, геометрии, 2009)
    We prove that every closed orientable three-manifold admits a parabolic foliation.
  • Planar Lebesgue Measure of Exceptional Set in Approximation of Subharmonic Functions 
    Girnyk, M. (Журнал математической физики, анализа, геометрии, 2009)
    We consider the pointwise approximation of a subharmonic function having ¯nite order by the logarithm of the modulus of an function up to a bounded quantity. We prove an estimate from below of the planar Lebesgue measure ...
  • Plancherel Measure for the Quantum Matrix Ball-1 
    Bershtein, O.; Kolisnyk, Ye. (Журнал математической физики, анализа, геометрии, 2009)
    The Plancherel formula is one of the celebrated results of harmonic analysis on semisimple Lie groups and their homogeneous spaces. The main goal of this work is to ¯nd a q-analogue of the Plancherel formula for spherical ...
  • Properties of Characteristic Function of Commutative System of Unbounded Nonselfadjoint Operators 
    Zolotarev, V.A. (Журнал математической физики, анализа, геометрии, 2010)
    A class of characteristic functions corresponding to commutative systems of unbounded nonselfadjoint operators is studied. The theorem on unitary equivalence is proved. The class of functions corresponding to these commutative ...
  • Properties of Modified Riemannian Extensions 
    Gezer, A.; Bilen, L.; Cakmak, A. (Журнал математической физики, анализа, геометрии, 2015)
    Let M be an n-dimensional differentiable manifold with a symmetric connection ∇ and T*M be its cotangent bundle. In this paper, we study some properties of the modified Riemannian extension ğ∇, c on T*M defined by means ...
  • Radon-Nikodým Theorems for Multimeasures in Non-Separable Spaces 
    Cascales, B.; Kadets, V.; Rodríguez, J. (Журнал математической физики, анализа, геометрии, 2013)
    We prove two Radon-Nikodým theorems for multimeasures using setvalued Pettis integrable derivatives. The first one works for dominated strong multimeasures taking convex compact values in a locally convex space. The second ...
  • Rate of Decay of the Bernstein Numbers 
    Plichko, A. (Журнал математической физики, анализа, геометрии, 2013)
    We show that if a Banach space X contains uniformly complemented l₂ⁿ 's then there exists a universal constant b = b(X) > 0 such that for each Banach space Y, and any sequence dn ↓ 0 there is a bounded linear operator T : ...
  • Real Hypersurfaces in Complex Two-Plane Grassmannians with Generalized Tanaka-Webster Invariant Shape Operator 
    Jeong, I.; Pak, E.; Suh, Y.J. (Журнал математической физики, анализа, геометрии, 2013)
    In this paper, we introduce a new notion of the generalized Tanaka-Webster invariant for a hypersurface M in G₂(C^m+2), and give a non-existence theorem for Hopf hypersurfaces in G₂(C^m+2) with generalized Tanaka-Webster ...

    Diskant, V.I. (Журнал математической физики, анализа, геометрии, 2014)
  • Renormalized Solutions for Nonlinear Parabolic Systems in the Lebesgue{Sobolev Spaces with Variable Exponents 
    El Hamdaoui, B.; Bennouna, J.; Aberqi, A. (Журнал математической физики, анализа, геометрии, 2018)
    The existence result of renormalized solutions for a class of nonlinear parabolic systems with variable exponents. The main contribution of our work is the proof of the existence of renormalized solutions without the ...
  • Retroreflecting Curves in Nonstandard Analysis 
    Almeida, R.; Neves, V.; Plakhov, A. (Журнал математической физики, анализа, геометрии, 2009)
    We present a direct construction of retroreflecting curves by means of Nonstandard Analysis. We construct non self-intersecting curves which are of class C¹, except for a hyper-finite set of values, such that the probability ...

    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.

    Gorkavyy, V.O.; Nevmerzhitska, O.M. (Журнал математической физики, анализа, геометрии, 2009)
    Two-dimensional ruled surfaces in the spaces of constant curvature Rⁿ, Sⁿ, Hn and in the Riemannian products Sⁿ x R¹, Hⁿ x R¹ are considered. A ruled surface is proved to represent a pseudospherical congruence if and only ...

    Poulin, Ph. (Журнал математической физики, анализа, геометрии, 2008)

  • Scattering Scheme with Many Parameters and Translational Models of Commutative Operator Systems 
    Zolotarev, V.A. (2007)
    The scattering scheme with many parameters for a commutative system of linear bounded operators {T1; T2}, when T1 is a contraction, is built. Using this construction of the scattering scheme, the translation model of the ...
