On some boundary value problems for linear multidimensional hyperbolic equations of the second order
For the linear hyperbolic equations \[\sum_{i,j=1}^{m+1} a_{ij}(x,x_{m+1})u_{x_ix_j}+\sum_{i=1}^{m+1} a_i(x,x_{m+1})u_{x_i}+c(x,x_{m+1})u=0, \] \[x=(x_1,\dots,x_m), \, m\geq2\] the correctness of multidimensional analogues of the problems of Darboux and Goursat is established and a theorem on the un...

\[\sum_{i,j=1}^{m+1} a_{ij}(x,x_{m+1})u_{x_ix_j}+\sum_{i=1}^{m+1} a_i(x,x_{m+1})u_{x_i}+c(x,x_{m+1})u=0, \]

A. Алдашев , С. А. - For the linear hyperbolic equations \[\sum_{i,j=1}^{m+1} a_{ij}(x,x_{m+1})u_{x_ix_j}+\sum_{i=1}^{m+1} a_i(x,x_{m+1})u_{x_i}+c(x,x_{m+1})u=0, \] \[x=(x_1,\dots,x_m), \, m\geq2\] the correctness of multidimensional analogues of the problems of Darboux and Goursat is established and a theorem on the uniqueness of a solution of the Cauchy characteristic problem is proved. Для линейных гиперболических уравнений \[\sum_{i,j=1}^{m+1} a_{ij}(x,x_{m+1})u_{x_ix_j}+\sum_{i=1}^{m+1} a_i(x,x_{m+1})u_{x_i}+c(x,x_{m+1})u=0,\] \[x=(x_1,\dots,x_m), \, m\geq2\] установлены корректности многомерных аналогов задач Дарбу и Гурса, а также доказана теорема единственности решения характеристической задачи Коши. Для лінійних гіперболічних рівнянь \[\sum_{i,j=1}^{m+1} a_{ij}(x,x_{m+1})u_{x_ix_j}+\sum_{i=1}^{m+1} a_i(x,x_{m+1})u_{x_i}+c(x,x_{m+1})u=0, \] \[x=(x_1,\dots,x_m), \, m\geq2\] досліджена коректність багатовимірних аналогів задач Дарбу і Гурса, а також доведена теорема єдності розв’язку характеристичної задачі Коші.
