AI 中文摘要
在CCSK(CCS的可逆扩展)的语境下,我们研究不同类型的互模拟关系(强/弱、仅前向/可逆),并突出它们的差异与共性。尤其针对文献中此前未研究的弱可逆情形,我们提出两种变体,分别命名为定向互模拟和混合互模拟,具体取决于τ动作是否应与待匹配动作处于同一方向(前向/后向)。我们证明,混合互模拟是同余关系,且完全抽象掉τ动作。
英文摘要
In the context of CCSK, a reversible extension of CCS, we study different notions of bisimilarity (strong/weak, forward-only/reversible) and highlight their differences and commonalities. In particular, for the weak reversible case, not previously studied in the literature, we propose two variants, dubbed directional and mixed bisimilarity, depending on whether $τ$ actions should be in the same direction (forward/backward) as the action being matched or not. We show, in particular, that mixed bisimilarity is a congruence and completely abstracts away from $τ$ actions.
