КРАЕВАЯ ЗАДАЧА ДЛЯ НАГРУЖЕННОГО УРАВНЕНИЯ ЭЛЛИПТИКО-ГИПЕРБОЛИЧЕСКОГО ТИПА В ДВУСВЯЗНОЙ ОБЛАСТИ

We study the existence and uniqueness of the solution of one boundary value problem for the loaded elliptic-hyperbolic equation of the second order with two lines of change of type in double-connected domain. Similar results have been received by D.M.Kuryhazov, when investigated domain is one-connected
