On isolated singularities for the stationary Navier-Stokes system (Q6638193)

This is a contribution to the study of removable singularities of the stationary Navier-Stokes equations with no exterior forces in \(n\ge 3\) dimensions. More precisely, some new results are proved related to the problem whether distributional solutions on a punctured ball in \(\mathbb R^n\) are also distributional solutions on the whole ball. These results extending classical Shapiro and Šverak are sharp as the famous Landau solutions in \(\mathbb R^3\setminus\{0\}\) show.
