Singularities of a compressible Stokes system in a domain with concave edge in \(\mathbb R^{3}\)
The author studies a compressible Stokes system in a three dimensional domain. One assumption on the domain is the assumption that is has a concave edge. He subtracts an edge singularity from the velocity and proves an increased regularity for remainder after the singularity has been subtracted. Making use of the transport character of the continuity equation he shows the propagation of the edge singularity into the interior of the considered domain.
