  • Groups with finiteness conditions on some subgroup systems: a contemporary stage 
    Dixon, M.R.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2009)
    This paper gives a brief historical survey of results in which certain systems of subgroups of a group satisfy various finiteness conditions.
  • Groups with many generalized FC-subgroup 
    Russo, A.; Vincenzi, G. (Algebra and Discrete Mathematics, 2009)
    Let FC⁰ be the class of all finite groups, and for each non-negative integer n define by induction the group class FCⁿ⁺¹ consisting of all groups G such that the factor group G/CG(xG) has the property FCⁿ for all elements ...
  • Groups with many pronormal and transitively normal subgroups 
    Kurdachenko, L.A.; Semko (Jr.), N.N.; Subbotin, I.Ya. (Algebra and Discrete Mathematics, 2012)
    A subgroup H of a group G is said to be transitively normal in G, if H is normal in every subgroup K ≥ H such that H is subnormal in K. We described some infinite groups, whose non–finitely generated subgroups are transitively ...
  • Groups with many pronormal and transitively normal subgroups 
    Semko (Jr.), N.N. (Algebra and Discrete Mathematics, 2013)
    A subgroup H of a group G is said to be transitively normal in G, if H is normal in every subgroup K ≥ H such that H is subnormal in K. The study of radical groups, whose not finitely generated subgroups are transitively ...
  • Groups with many self-normalizing subgroups 
    M. De Falco; F. de Giovanni; Musella, C. (Algebra and Discrete Mathematics, 2009)
    This paper investigates the structure of groups in which all members of a given relevant set of subgroups are selfnormalizing. In particular, soluble groups in which every nonabelian (or every infinite non-abelian) subgroup ...
  • Groups with small cocentralizers 
    Javier Otal; Semko, N.N. (Algebra and Discrete Mathematics, 2009)
    Let G be a group. If S⊆G is a G-invariant subset of G, the factor-group G/CG(S) is called the cocentralizer of S in G. In this survey-paper we review some results dealing with the influence of several cocentralizers on the ...
  • Groups with the minimal condition for nonabelian subgroups 
    Chernikov, N.S. (2006)
    Для деяких дуже широких класiв D i B ⊂ D груп автор доводить, що довiльна (неабелева) група G ∊ D (вiдповiдно, G ∊ B) задовольняє умову мiнiмальностi для (неабелевих) пiдгруп тодi i тiльки тодi, коли вона є чернiковською.
  • Groups with the same prime graph as the simple group Dn(5) 
    Babai, A.; Khosravi, B. (Український математичний журнал, 2014)
    Let G be a finite group. The prime graph of G is denoted by Γ(G). Let G be a finite group such that Γ(G)=Γ(Dn(5)), where n≥6. In the paper, as the main result, we show that if n is odd, then G is recognizable by the prime ...
  • Groups with Various Minimal Conditions on Subgroups 
    Dixon, M.R.; Evans, M.J.; Smith, H. (Український математичний журнал, 2002)
    We briefly review some recent works on groups with the weak minimal condition on nonnilpotent subgroups. We also study the class of groups with the weak minimal condition on non-(soluble of derived length d) subgroups.
  • Growth and representation of analytic and harmonic functions in the unit disc 
    Chyzhykov, I. (Український математичний вісник, 2006)
  • Grüss-type and Ostrowski-type inequalities in approximation theory 
    Acu, A.-M.; Gonska, H.; Rasa, I. (Український математичний журнал, 2011)
    We discuss the Grass inequalities on spaces of continuous functions defined on a compact metric space. Using the least concave majorant of the modulus of continuity, we obtain a Grass inequality for the functional L(f)=H(f;x), ...
  • G-Strands and Peakon Collisions on Diff(R) 
    Holm, D.D.; Ivanov, R.I. (Symmetry, Integrability and Geometry: Methods and Applications, 2013)
    A G-strand is a map g: R×R→G for a Lie group G that follows from Hamilton's principle for a certain class of G-invariant Lagrangians. Some G-strands on finite-dimensional groups satisfy 1+1 space-time evolutionary equations ...
  • G-Supplemented Modules 
    Koşar, B.; Nebiyev, C.; Sökmez, N. (Український математичний журнал, 2015)
    Following the concept of generalized small submodule, we define g -supplemented modules and characterize some fundamental properties of these modules. Moreover, the generalized radical of a module is defined and the ...
  • Gustafson-Rakha-Type Elliptic Hypergeometric Series 
    Rosengren, H. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    We prove a multivariable elliptic extension of Jackson's summation formula conjectured by Spiridonov. The trigonometric limit case of this result is due to Gustafson and Rakha. As applications, we obtain two further ...
  • Gyrogroups and left gyrogroups as transversals of a special kind 
    Kuznetsov, E. (Algebra and Discrete Mathematics, 2003)
    In this article we study gyrogroups and left gyrogroups as transversals in some suitable groups to its subgroups. These objects were introduced into consideration in a connection with an investigation of analogies between ...
  • (G,ϕ) -crossed product on (G,ϕ)-quasiassociative algebras 
    Mamede Albuquerque, H.M.; Félix Barreiro, M.E.; Sánchez Delgado, J.M. (Algebra and Discrete Mathematics, 2017)
    The notions of (G,ϕ)-crossed product and quasicrossed system are introduced in the setting of (G,ϕ)-quasiassociative algebras, i.e., algebras endowed with a grading by a group G, satisfying a ``quasiassociative'' law. It ...
  • G-оценка квадратичной дискриминантной функции 
    Гирко, В.Л.; Павленко, Т.В. (Український математичний журнал, 1989)
  • G-сходимость параболических операторов и слабая сходимость решений диффузионных уравнений 
    Махно, С.Я. (Український математичний журнал, 1993)
    The upper estimates and, in some special cases, the lower estimates of the rate of rational approximation of piecewise-analytic functions defined on touching continuums are established. The upper and the lower estimates ...
  • G-сходимость параболических периодических операторов с малым параметром при производной по времени 
    Сиденко, Н.Р. (Український математичний журнал, 1993)
  • G-функции Бесселя. І 
    Турбин, А.Ф.; Плоткин, Я.Д. (Український математичний журнал, 2001)
    Введено повий клас спеціальних функцій, що узагальнюють класичні функції Бесселя, та доведено їх основні властивості.
