## On the stationary Oseen equations in $$\mathbb R^3$$.(English)Zbl 1235.35216

Summary: The stationary Oseen equations are studied in $$\mathbb R^3$$ in its general form, that is, with a non-constant divergenceless function on the convective term. We prove existence, uniqueness and regularity results in weighted Sobolev spaces. From this new approach, we also state existence, uniqueness and regularity results for the generalized Oseen model which describes the rotating flows. The proofs are based on Laplace, Stokes and Oseen theories.
