From the author’s abstract: Function spaces with weighted norms and detached asymptotics naturally appear in the treatment of boundary-value problems when linear and nonlinear terms have the same asymptotic behaviour either at a singularity point of the boundary, or at infinity. The characteristic feature of these spaces is that their norms are composed from both, norms of angular parts in the detached terms and norms of asymptotic remainders. The developed approach is described for the Navier-Stokes problems in domains with conical (angular) outlets to infinity while the 3-D exterior and 2-D aperture problems imply representative examples. With a view towards compressible and non-Newtonian fluids, the described technique is applied to the transport equation as well.
