On the polynomial approximation of solution for the Cauchy problem

The Cauchy problem for a nonhomogeneous first-order differential-operator equation of parabolic type in a Hilbert space is considered. Polynomial approximations and estimates of their convergence are obtained which depend on the character of the right-hand side and the initial conditions.

Исмаилов , З. И. - The Cauchy problem for a nonhomogeneous first-order differential-operator equation of parabolic type in a Hilbert space is considered. Polynomial approximations and estimates of their convergence are obtained which depend on the character of the right-hand side and the initial conditions. Рассматривается задача Коши для неоднородного дифференциально-операторного уравнения первого порядка параболического типа в гильбертовом пространстве. В зависимости от характера правой части и начальных условий получены полиномиальные приближения и оценки их сходимости. Розглядається задача Коші для неоднорідного диференціально-операторного рівняння першого порядку параболічного типу у гільбертовому просторі. В залежності від характеру правої частини і початкових умов одержані поліноміальні наближення і оцінки їх збіжності.
