  • Some commutativity criteria for 3-prime near-rings 
    Raji, A. (Algebra and Discrete Mathematics, 2021)
    In the present paper, we introduce the notion of *-generalized derivation in near-ring N and investigate some properties involving that of *-generalized derivation of a *-prime near-ring N which forces N to be a commutative ...
  • Some Comparison Theorems in Finsler--Hadamard Manifolds 
    Borisenko, A.A.; Olin, E.A. (2007)
    We give upper and lower bounds for the ratio of the volume of metric ball to the area of metric sphere in Finsler-Hadamard manifolds with the pinched S-curvature. We apply these estimates to find the limit at infinity for ...

  • Some criteria of boundedness of the L-index in direction for slice holomorphic functions of several complex variables 
    Bandura, A.; Skaskiv, O. (Український математичний вісник, 2019)
    We investigate the slice holomorphic functions of several complex variables that have a bounded L-index in some direction and are entire on every slice {z⁰ + tb : t ∈ C} for every z⁰ ∈ Cⁿ and for a given direction b ∈ Cⁿ ...

    Soldatova, E.D.; Galachenko, T.E. (Condensed Matter Physics, 2006)
    The relations between the critical exponents of basic stability characteristics are obtained based on the thermodynamic stability requirements for the generalized one-component system without engaging any hypotheses. The ...
  • Some features of polarization modulation in spectroscopy of optical and photoelectric effects 
    Kondratenko, S.V.; Matyash, I.A.; Serdega, B.K. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2004)
    We analyze usage of modulation of electromagnetic radiation polarization in investigations of optical and photoelectric effects in anisotropic crystals. It is shown that when transmission spectra are studied with the ...

    For the past decades the microwave radiometry is a routinely used as diagnostic tool to obtain the information on temporal evolution and radial profile of the electrons temperature at Uragan-3M torsatron plasma experiments. ...
  • Some features of transverse photovoltage in semiconductor heterostructure and Schottky contact 
    Shekhovtsov, L.V. (Semiconductor Physics Quantum Electronics & Optoelectronics, 2001)
