Abstract
I will survey and talk about corner singularity and regularity results for the compressible Stokes flows around corner, cut and edge boundaries. I have worked the issues over 20 years. I will try to describe a whole picture for the issues from a very simple idea to complicated problems. Mechanical or dynamical problems usually have very singular boundaries for flow domains, for instance, imagine blood vessels, wings and front or rear portions of aircrafts, etc. Such singular boundaries generate diverse flow behaviors, acoustic noises (disturbances), exert strong influences on stable movements and eventually bring us fatal damages. Hence precise analysis and understanding are necessary. I will mention known results and open questions.
