      Sadiq, Shama; Azhar, Nadeem; Myrzakulov, N.; Toktarbay, S.; Muratkhan, A.; Shaymatov, Sanjar; Jawad, Abdul (Nuclear Physics, Section B, 2025)
      This research explores the rapid expansion period of the early universe by applying the Chaplygin gas model, an alternative cosmological framework, to analyze the dynamics of inflationary processes. This study assesses the compatibility of three widely studied scalar field potentials with the latest observational constraints derived from the Planck datasets. Our analysis includes ...

    • Darboux transformation and soliton solution for generalized Konno-Oono equation 

      Bekova, G; Shaikhova, G; Yesmakhanova, K; Myrzakulov, R (Journal of Physics: Conference Series, 2019)
      In this paper, the generalized Konno-Oono equation is investigated. Using the Lax pair, we obtain a new Darboux transformation for the dispersionless equation. A soliton solution of the generalized Konno-Oono equation is obtained on the basis of the Darboux transformation. Corresponding graphs are also built.

    • Dark energy and dark matter configurations for wormholes and solitionic hierarchies of nonmetric Ricci flows and F( R, T, Q, Tm) gravity 

      Bubuianu, Laurenţiu; Vacaru, Sergiu I.; Veliev, Elşen Veli; Zhamysheva, Assel (The European Physical Journal C, 2024)
      We extend the anholonomic frame and connection deformation method, AFCDM, for constructing exact and parametric solutions in general relativity, GR, to geometric flow models and modified gravity theories, MGTs, with nontrivial torsion and nonmetricity fields. Following abstract geometric or variational methods, we can derive corresponding systems of nonmetric gravitational and ...

    • Data-mining и перспективы применения в аудите: вызовы и преимущества 

      Каирканова, Зульфия Раисовна; Аманова, Гульнара Дюсембаевна (Л.Н.Гумилев атындағы Еуразия ұлттық университеті, 2025-02-21)
      Аудит представляет собой процесс оценки предмета с целью высказывания мнения о его справедливости, проводимый независимым специалистом. Важность оценки справедливости финансовой отчетности заключается в конфликте интересов между теми, кто составляет отчеты, и заинтересованными сторонами. В ходе аудита обычно применяется выборочный метод для сбора данных, что обусловлено ...
