FILLIPE MANOEL XAVIER RESINA2025-01-212025-01-212021https://repositorio.insper.edu.br/handle/11224/7254One of AGM revision’s main properties is success, which guarantees that new information is always accepted by a rational agent, even when it has to give up a reasonable belief previously held. However, in more realistic scenarios, when dealing with a new belief that contradicts previous ones, an agent has the option to reject it. Selective Revision, then, came up as a third possibility, allowing the agent to accept only part of a new belief. Selective Revision was initially defined for single sentences as inputs but, in many situations, new pieces of information come simultaneously (a set of beliefs). This paper proposes a generalization of Selective Revision to the multiple case for both belief sets (theories) and belief bases. We provide constructions, postulates and representation theorems for different classes of Multiple Selective RevisionDigitalInglêsconference paper
