On a class of elliptic operators with nonpolynomial degeneracy on a boundary (Q1204770)

This article presents a new Fredholm solvability theorem for elliptic differential operators of order \(m\) on bounded smooth domains \(\Omega \subset \mathbb{R}^ n\) with continuous but degenerating on \(\partial \Omega\) coefficients. The theorem presented covers cases when the coefficients have either normal or tangent degeneration.
