ON A PROBLEM FOR A QUASI-LINEAR ELLIPTIC EQUATION WITH TWO PERPENDICULAR LINES OF DEGENERACY
Main Article Content
Abstract
The study of quasi-linear equations of elliptic, hyperbolic and mixed types is important because they are interesting both theoretically and practically. Boundary value problems for such equations with one line of degeneracy are studied in [1-2]. However, boundary value problems for equations with two lines of degeneracy are poorly studied. Note the works [3-5]. This paper is devoted to the study of a boun-dary value problem for a quasi-linear elliptic equation with two degeneracy lines.
