Abstract:
A representation of the solution to an elliptic boundary value problem in the vicinity of a corner point on the discontinuity line of the coefficient of the higher order derivative is constructed. The study is based on the method of additive separation of singularities proposed by Kondrat’ev.
Key words:elliptic boundary value problems, corner point on the discontinuity line, additive separation of singularities, numerical methods for singularity separation, waveguide problems.
