Non-local boundary value problems for parabolic equations, including the equations of thermal conductivity, have been the object of research for a long time. Interest in such problems is caused by the need for further development of the theory of boundary value problems with displacement (Nakhushev's problems), as well as in connection with their numerous applications. This article is devoted to the study of the question of the unambiguous solvability of one class of nonlocal boundary value problems for the heat equation. The problem of finding a regular solution of the thermal conductivity equation with a fractional Riemann – Liouville derivative under boundary conditions is considered. The Cauchy problem for an equation equivalent to the original equation is considered, and it is proved that the boundary value problem under consideration is reduced to the first boundary value problem for the heat equation, provided that the Cauchy problem has a unique solution in the class of functions satisfying the conditions of A. N. Tikhonov. In this case, the solution is represented as an integral equation containing the Barrett function in the kernel. Also, by reducing to a system of differential equations with a fractional Riemann-Liouville derivative, the question of the uniqueness and existence of a solution to the problem is solved when the values of the solution at the other end are in the condition. The results obtained in this work will serve as a basis for further research of nonlocal boundary value problems for parabolic differential equations underlying mathematical modeling of processes in systems with fractal structure, as well as the development of the theory of fractional differential equations.
Keywords: class of nonlocal boundary value problems, Tikhonov conditions, regular solution, Cauchy problem, homogeneous problem, fractional differentiation operator, fractional differential equations.
