A Variety of DeMorgan Negations in Relevant Logics
نویسندگان
چکیده
The present paper is inspired by Sylvan and Plumwood’s logicBM defined in “Non-normal relevant logics” their treatmentof negation with the ∗-operator “The semantics of first-degree en-tailment”. Given a positive logic L including Routley Meyer’sbasic included either fragment Eor that RW, we investigate essential De Morgan ex-pansions determine all deductive relations they maintainto each other. A Routley-Meyer provided for logicdefined paper.

Notes on the Model Theory of DeMorgan Logics
We make preliminary investigations into the model theory of DeMorgan logics, attempting to make a case for the worth of such investigations before tackling the plight of particular mathematical theorems in these logics. We demonstrate that Loś’ Theorem holds with respect to these logics and make some remarks about standard model-theoretic properties in such contexts. More concretely, as a case ...
متن کاملCTL Model-Checking over Logics with Non-Classical Negations
In earlier work [9], we defined CTL model-checking over finite-valued logics with De Morgan negation. In this paper, we extend this work to logics with intuitionistic, Galois and minimal negations, calling the resulting language CTL. We define CTL operators and show that they can be computed using fixpoints. We further discuss how to extend our existing multi-valued model-checker Chek [8] to re...

متن کاملInformation Flow and Relevant Logics
2 Routley-Meyer Frames Relevant logics are interesting things. One motivating principle for these logics is the requirement that if a conditional of the form ! is to be true, there must be a connection between and . The antecedent must somehow be relevant to the consequent . This is simple to chart prooftheoretically, and for years, this was how relevant logics were studied. (A great deal of th...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
