  • THE CAUCHY PROBLEM FOR A MOLECULAR BEAM EPITAXY MODEL WITH SLOPE SELECTION 
    Biyar, Magzhan (Nazarbayev University School of Sciences and Humanities, 2021-05)
    This thesis is devoted to the study of a nonlinear diffusion equation. We have to prove that the Cauchy problems for a molecular beam epitaxy (MBE) equation with slope selection is locally well-posed for initial data in 𝑊...
  • EXPERIMENTAL STUDY OF MANIFOLD LEARNING AND TANGENT PROPAGATION 
    Ashimov, Temirlan (Nazarbayev University School of Sciences and Humanities, 2021-05)
    In the Data Science routine, we often face the curse of dimensionality, dealing with high-dimensional data which, in turn, can be very difficult. The problems of this nature can be approached by methods of Dimensionality ...
  • MODELING AND NUMERICAL ANALYSIS OF GRAPHENE MICROBEAM RESONATOR 
    Yessetov, Yerkebulan (School of Sciences and Humanities, 2023-07)
    Microelectromechanical systems (MEMS) have emerged as a revolutionary technology, enabling the development of miniaturized devices with diverse functionalities and superior performance. Among the essential components of ...
  • PHYSICS INFORMED NEURAL NETWORKS FOR SOLVING DIRAC EQUATION IN (1+1) DIMENSION 
    Bazarkhanova, Aigerim (Nazarbayev University School of Sciences and Humanities, 2021-05-13)
    The Dirac equation plays a fundamental role in quantum physics and its exact solutions are of utmost importance. In this study we solved Linear and Nonlin ear Dirac equation in (1+1) dimension and obtained analytical ...
  • THE REDISCOVERY HYPOTHESIS: LANGUAGE MODELS NEED TO MEET LINGUISTICS 
    Maxat, Tezekbayev (Nazarbayev University School of Sciences and Humanities, 2022-05)
    There is an ongoing debate in the NLP community whether modern language models contain linguistic knowledge, recovered through so-called probes. This work examines whether linguistic knowledge is a necessary condition ...
  • REMAINDERS OF THE HIGHER-ORDER POINCAR´E INEQUALITIES FOR BAOUENDI-GRUSHIN VECTOR FIELDS 
    Kabduali, Bek (Nazarbayev University School of Sciences and Humanities, 2022-05)
    The main result of this thesis work is a proof of the higher-order Poincar´e inequalities for Baouendi-Grushin vector fields on non-smooth domains. The finding is successfully applied to the study of the higher-order ...
