Course description and aims

This course gives lecture on mathematical analysis for hyperbolic systems of balance laws. We develope the general mathematical theory on the global existence and asymptotic stability of solutions.

The aim of this course is as follows. We treat hyperbolic systems of balance laws as nonlinear partial differential equations. We formulate structural conditions on the system and under these structural conditions, we prove the global existence and asymptotic stability of solutions for small initial data. The proof is based on the energy method and the semigroup technique.
