Stokes operator

The Stokes operator is a mathematical operator that arises in the study of fluid dynamics and the Navier-Stokes equations, which describe the motion of viscous fluid substances. The Stokes operator specifically relates to the study of the stationary Stokes equations, which can be viewed as a linear approximation of the Navier-Stokes equations for incompressible flows at low Reynolds numbers (where inertial forces are negligible compared to viscous forces).
