Meet-simulations distinguish themselves from simulations because they relate pairs of states from one model to single states from another. En route to this result we use a more traditional notion of simulations and prove a Hennessy-Milner style theorem for it, using an analogue of modal saturation called meet-compactness.", "revisions": [ { "version": "v1", "updated": "2022-08-24T08:05:27.000Z" } ], "analyses": { "keywords": [ "first-order logic", "semilattices", "hennessy-milner style theorem", "single-sorted first-order language", "relate pairs" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
