Analysis of Some Boundary Value Problems for Mixed-Type Equations with Two Lines of Degeneracy

The article provides an overview of the practical significance of boundary value problems for mixed-type equations. methods for solving boundary value problems for a mixed-type equation with two degeneracy lines are analyzed and compared for cases when the degree of variables coefficients before second-order derivatives is the same and different. The problems arising in their solution are discussed.
