Abstract

Исследована краевая задача со смещением для неоднородного уравнения параболо-гиперболического типа третьего порядка с волновым оператором в области гиперболичности, когда в качестве одного из граничных условий задана линейная комбинация с переменными коэффициентами производных от значений искомой функции на независимых характеристиках, а также на линии изменения типа и порядка. Найдены необходимые и достаточные условия существования и единственности регулярного решения задачи. В некоторых частных случаях представление решения исследуемой задачи выписано в явном виде.

Highlights

  • In the article, we investigate a boundary-value problem with a thirdorder inhomogeneous parabolic-hyperbolic equation with a wave operator in a hyperbolicity domain

  • Equation (1) is parabolic-hyperbolic equation with type and order degeneration along the line y = 0 and, as stated in [3], study of boundary value problems for the above equations brings a new aspect to the mixed type equations theory

  • We study the displacement boundary value problem for inhomogeneous parabolic-hyperbolic equation of the third order (1) and a third-order parabolic and wave equations in the hyperbolicity domain
