The Oseen system with nonhomogeneous boundary conditions in polyhedral or polygonal domains
Mehdi Badra, Jean‐Pierre Raymond · HAL (Le Centre pour la Communication Scientifique Directe) · 2025
We consider the Oseen system with nonhomogeneous boundary conditions in a bounded Lipschitz polyhedron in R 3 or a bounded Lipschitz polygon in R 2 . We prove new regularity results for regular and irregular boundary conditions, for both a convex or non-convex polyhedron in R 3 and a convex or non-convex polygon in R 2 .
