This paper provides a comprehensive stability analysis for parabolic Allen-Cahn systems, examining analytical and numerical stability properties. It focuses on energy dissipation, long-time behavior, and metastable dynamics, establishing stability criteria for various time-discretization methods and characterizing the slow motion of transition layers.
Key findings
