| Research Abstract |
In this study we have considered Navier-Stokes equations describing incompressible viscous fluid flow in the domain with a corner point. We assume that flow under consideration is parallel and analyze the problem in a plane sector. For the linearized equation which neglect the nonlinear term (convection term) we succeed to classify the order of the singularity of the solution near the corner according to the width of the angle. The result is in preparation for publication.
