A mixed problem for the wave equation in coordinate domains.I.Mixed problem for the wave equation in a quadrant

A formal solution from the class [Java Applet] to the mixed problem for the classic wave equation in the coordinate corner [Java Applet] with boundary conditions of an oblique derivative type is found in the first part of this article. The solution is found for all values of parameters of the boundary conditions such that the Lopatinsky condition is fulfilled on every boundary. The energy inequality (an a priori estimation in [Java Applet]) without loss of generality is proved provided that the right hand sides are finite and the uniform Lopatinsky condition is fulfilled. The second part of this article will be published in the next issue of journal.
