Partiality without the Cost Partiality without the Cost
Even though it is not very often admitted, partial functions do play a signiicant role in many practical applications of deduction systems. Kleene has already given a semantic account of partial functions using a three-valued logic decades ago, but there has not been a satisfactory mechanisation. Based on this, we have developed resolution and tableau calculi for automated theorem proving. The ...
متن کاملApproval Voting and Parochialism
In hypothetical scenarios involving two groups (nations or groups of workers), subjects voted on three proposals: one helped group A (their group), one helped B, and one helped both groups, more than the average of the first two but less than their maximum. When subjects voted for one proposal, most voted for the one that helped group A. This result is “parochial” because it helps the voter’s o...
متن کاملMechanising Partiality without Re-implementation Mechanising Partiality without Re-implementation
Even though it is not very often admitted, partial functions do play a signii-cant role in many practical applications of deduction systems. Kleene has already given a semantic account of partial functions using a three-valued logic decades ago. This approach allows rejecting certain unwanted formulae as faulty, which the simpler two-valued ones accept. We have developed resolution and tableau ...
متن کاملMeaning and Partiality Revised
Muskens presents in Meaning and Partiality a semantics of possibly contradictory beliefs and other propositional attitudes. We propose a different partial logic based on a few key equalities for the connectives and with four values (truth, falsehood, and undefinedness with negative and positive polarity; only the first truth value is designated). Aim and Scope In logical semantics the grammar a...
متن کاملQuantiiers and Partiality
1 Varieties of Partiality Quantiication can involve partiality in several ways. Quantiiers loaded with presuppositions give rise to partiality by introducing truth value gaps (if there are no A, and the quantiier all + carries an existence presupposi-tion, then all + A are B will lack a truth value). The study of quantiiers in contexts of incomplete information involves a quite diierent kind of...
