A Calculus of Boundary Value Problems in Domains with Non–Lipschitz Singula Points |
|
| Authors: | Vladimir Rabinovich Bert‐Wolfgang Schulze Nikolai Tarkhanov |
| Abstract: | The paper is devoted to pseudodifferential boundary value problems in domains with singular points on the boundary. The tangent cone at a singular point is allowed to degenerate. In particular, the boundary may rotate and oscillate in a neighbourhood of such a point. We show a criterion for the Fredholm property of a boundary value problem and derive estimates of solutions close to singular points. |
