5. A class of inverse source problems for a parabolic equation with nonlocal initial and boundary conditions was investigated. The peculiarity of the class of problems is that the recovered parameters depend only on the time or space variable. To solve the considered problems, an iterative numerical method based on the straight line method and a special indication of the solution of the obtained auxiliary boundary problems was proposed. The software was developed. Computer experiments on the test problems were conducted.

6. The optimal Bolza control problem specified by higher-order and phase-limited differential inclusions was investigated. Adequate optimality conditions were obtained using the additive differential Mahmudov inclusion, which is a generalization of Euler-Lagrange inclusions and transversality conditions, as well as the classical Euler-Poisson equation of the theory of calculus of variations. The results obtained may find a variety of practical applications in solving the problems of economic process control, in particular, the described polyhedral differential inputs in the framework of the well-known Neumann-Gale economic model.

7. For joint investigation of problems of classification of user queries, construction of the language model and identification of names of beings in the dialogue systems in the Azerbaijani language, the model of neural network based on the transformer was developed. The objective function used for training of the proposed neural network was minimized as a convolution of the objective functions of the above problems. The paper shows that the neural network built in this way gives more satisfactory results in this area, because it simultaneously studies the language model describing the domain of application, along with the identification of the user query.
