摘要 认知状态的概念被引入作为信念改变所建议的常见表征的概括。在此基础上，定义了一类新的对应于信念收缩的非单调推理关系。建立了许多代表性结果，涵盖传统的 AGM 收缩和不满足恢复的收缩。
Abstract A notion of an epistemic state is introduced as a generalization of common representations suggested for belief change. Based on it, a new kind of nonmonotonic inference relation corresponding to belief contractions is defined. A number of representation results is established that cover both traditional AGM contractions and contractions that do not satisfy recovery.
