On pointwise decay of linearized stationary incompressible viscous flow around rotating and translating bodies. (English) Zbl 1231.35143
The authors consider a system arising after linearization of a model of stationary viscous incompressible flow past a translating and rotating rigid body. They derive a representation formula for the velocity field and use it to obtain pointwise decay estimates and to identify a leading term with respect to this decay. Finally a representation theorem for weak solutions of the stationary Navier-Stokes system with Oseen and rotational terms is obtained.
