The method is based on the operational solution of the initial problem with an initial function of general form satisfying the Dirichlet condition and a homogeneous boundary condition of the third kind. On the basis of the obtained relations, a series of analytical solutions of the third boundary value problem for a parabolic equation in various equivalent functional forms is proposed. An integral representation of the analytic solutions of the third boundary-value problem is proposed for the general form of the representation of boundary-value functions in the initial formulation of the problem. The corresponding Green's function is written out.</p></abstract><trans-abstract xml:lang="ru"><p>Развита математическая теория построения интегрального преобразования и формулы обращения для него для третьей краевой задачи в области с непрерывным спектром собственных значений. Метод основан на операционном решении исходной задачи с начальной функцией общего вида, удовлетворяющей условию Дирихле, и однородному граничному условию третьего рода. На основе полученных соотношений предложена серия аналитических решений третьей краевой задачи для уравнения параболического типа в различных эквивалентных функциональных формах. Предложено интегральное представление аналитических решений третьей краевой задачи при общей форме записи краевых функций в исходной постановке задачи.
