Course description and aims

This course gives the theory of bifurcation and stability for the compressible Navier-Stokes equations which are known to be the fundamental equations in the fluid mechanics. The compressible Navier-Stokes equations are classified in a class of quasilinear heyperbolic-parabolic systems and have provided fundamental issues in the field of partial differential equations such as existence, uniqueness, regularity and asymptotic behavior of solutions, and etc. In this course, the standard bifurcation theory for partial differential equations is firstly explained; and an application of this theory is illustrated by considering stationary bifurcation problems for the incompressilble Navier-Stokes equations which is classified in a class of parabolic systems. Secondly, stationary bifurcation problems for compressilble Navier-Stokes equations is considered, which cannot be treated by the standard bifurcation theory. This course will be completed with "Advanced topics in Analysis F" in the next quarter.

The aim of this course is to learn some aspects of mathematical analysis of nonlinear partial differential equations through the bifurcation and stability analysis of the Navier-Stokes equations.
