Non-local problems for parabolic-hyperbolic equations with deviation from the characteristics and three type-changing lines. (English) Zbl 1205.35169

Summary: We prove the existence and uniqueness of solutions for a partial differential equations of mixed type (parabolic-hyperbolic type). We use energy integrals and methods from integral equations to study a problem that has deviation from the characteristics and three lines where the type changes.
