С. А. Назаров, Maria Specovius‐Neugebauer · Banach Center Publications · 2008
This paper deals with a strongly elliptic perturbation for the Stokes equation in exterior three-dimensional domains $\Omega$ with smooth boundary. The continuity equation is substituted by the equation $-\varepsilon^2\Delta p + \mathop{\rm div} u =0$, an
