In some problems of fluid mechanics, it is possible to be confronted with\ndata that are not regular, that is why we are interested here in the search for\nthe so-called very weak solutions for the stationary Stokes problem with\nNavier-type boundary conditions in a three-dimensional exterior domain. The\nproblem describes the flow of a viscous and incompressible fluid past an\nobstacle where we assume that the fluid may slip on the boundary of the\nobstacle. Because the flow domain is unbounded, we set the problem in weighted\nSobolev spaces in order to control the behavior at infinity of the solutions.\nOur purpose is to prove the existence and the uniqueness of a very weak\nsolution in a Hilbertian framework.\n
