Dirichlet problem for an equation of mixed type with two degeneration lines in a rectangular domain

Autor: K. B. Sabitov, E. V. Vagapova

Publikováno v: Differential Equations. 49:68-78

For an equation of elliptic-hyperbolic type with two perpendicular lines of power-law degeneration, we prove a criterion for the uniqueness of the solution of the first boundary value problem by the spectral expansion method. The solution is construc
