  Zhakiyev, Nurkhat; Khamzina, Ayagoz; Zhakiyeva, Svetlana; Miglio, Rocco De; Bakdolotov, Aidyn; Cosmi, Carmelina (Energies, 2023)

  This research article provides a comprehensive scenario analysis of key structural changes in Kazakhstan’s fuel and energy complex subsectors until 2060, focusing on decarbonization efforts. The background places the ...
• On weighted integrability of the sum of series with monotone coefficients with respect to multiplicative systems 

  Turgumbaev, M.Zh.; Suleimenova, Z.R.; Tungushbaeva, D.I. (Bulletin of the Karaganda University. Mathematics Series, 2023)

  In this paper, we consider the questions about the weighted integrability of the sum of series with respect to multiplicative systems with monotone coefficients. Conditions are obtained for weight functions that ensure ...
• On the Resolvent Existence and the Separability of a Hyperbolic Operator with Fast Growing Coefficients in L2(R 2 ) 

  Muratbekova, Mussakan; Bayandiyev, Yerik (Faculty of Sciences and Mathematics, 2021)

  This paper studies the question of the resolvent existence, as well as, the smoothness of elements from the definition domain (separability) of a class of hyperbolic differential operators defined in an unbounded domain ...
• On the Fourier transform of functions from a Lorentz space L2,r with a mixed metric 

  Tleukhanova, N.T.; Mussabayeva, G.K.; Manarbek, M. (Bulletin of the Karaganda University. Mathematics Series, 2023)

  The classical inequalities of Bochkarev play a very important role in harmonic analysis. The meaning of these inequalities lies in the connection between the metric characteristics of functions and the summability of ...
