Abstract:

This paper is concerned with the convergence rates to travelling waves for
a relaxation model with general flux functions. Compared with former results in this
direction, the main novelty in this paper lies in the fact that the initial disturbance can be
chosen large in suitable norm. Our analysis is based on the L1-stability results obtained
by C. Mascia and R. Natalini in [12].

Key words: Convergence rate, relaxation, travelling waves, large initial disturbance
