  • Some new integral inequalities for (s;m)-convex and (а;m)-convex functions 
    Bayraktar, B.; Kudaev, V.Ch. (Ye.A.Buketov Karaganda State University Publishing house, 2019-06-28)
    The paper considers several new integral inequalities for functions the second derivatives of which, with respect to the absolute value, are (s;m)-convex and (а;m)-convex functions. These results are related to well-known ...
  • Splitting method and the existence of a strong solution of the Navier-Stokes equations 
    Akishev (Akysh), A.Sh. (Ye.A.Buketov Karaganda State University Publishing house, 2019-06-28)
    In the author’s article from the previous issue of the journal from the properties of the ONS solutions the relation between pressure and module square of velocity vector is set. Based on which the uniqueness of the weak ...
  • The atomic definable subsets of semantic model 
    Yeshkeyev, A.R.; Issaeva, A.K.; Mussina, N.M. (Ye.A.Buketov Karaganda State University Publishing house, 2019-06-28)
    In this paper some properties of small models, generally speaking, not necessarily complete theories and their relationship with each other were considered. Under small models we will understand some modifications of the ...
  • The J-minimal sets in the hereditary theories 
    Yeshkeyev, A.R.; Omarova, M.T.; Zhumabekova, G.E. (Ye.A.Buketov Karaganda State University Publishing house, 2019-06-28)
    Our attention in given article will be paid to the study of model-theoretic properties of hereditary Jonsson theories, while we consider Jonsson theories that retain jonsonness under any admissible enrichment. In given ...
  • The usage of the method of mathematical statistics in the process of optimization of the content of antifriction composite materials 
    Zinchenko, D.A.; Akimov, A.V.; Babii, M.V. (Ye.A.Buketov Karaganda State University Publishing house, 2019-06-28)
    The optimum content of microtalc (dispersion d = 7...10 μm) and silver carbonate (dispersion d = 0,5 μm) fillers in polymeric materials was determined by the method of mathematical statistics to form an adhesive and ...
  • Two-dimensional thermo-viscoelastic waves in layered media 
    Bukenov, M.M.; Adamov, A.A.; Mukhametov, Y.M. (Ye.A.Buketov Karaganda State University Publishing house, 2019-06-28)
    Dynamic problems of deformation of solids have been the subject of numerous studies in the CIS and abroad. The rejection of a number of simplifying assumptions made in the cited and other published works leads to the need ...
