Dynamics in argumentation

Argumentative reasoning evolves dynamically over time, and knowledge base revisions may become necessary in light of new information. Forgetting an assumption or enforcing a claim while preserving the structure of “irrelevant” knowledge can be challenging and sometimes even impossible. We investigate these changes and study questions like: what are the theoretical boundaries, minimal consistent changes, long-term equivalence behaviour of argumentation frameworks?
