Scattered Sentences have Few Separable Randomizations
... Scattered sentences were introduced by Morley [M], motivated by Vaught’s conjecture. The absolute form of Vaught’s conjecture for an Lω1 ω -sentence ϕ says that if ϕ is scattered then ϕ has countably many (non-isomorphic) countable models 1. In continuous logic, the pure randomization theory P R (fr ...

The final important property of first-order logic that we have to investigate is compactness: Given a set F of first-order formulas, what does the satisfiability of finite subsets tell us about the satisfiability of the whole set. In propositional logic we have shown that a set S is uniformly satisf ...

... One important distinction to make is that fuzzy logic is NOT probability. Although both employ values between 0 and 1 that represent something about the symbol or event, it is the meaning of this number that differs. In probability, the number represents the likelihood of an event’s occurrence. In f ...

On the other hand, it can serve as an answer to an howmany-of question, as in “how many of the students got an A?” Similarly it can serve as an answer to ...

Nair [7] gave a nice proof for the well-known estimate lcm{1, 2, . . . , n} ≥ 2n−1 , while Hanson [3] already obtained lcm{1, 2, . . . , n} ≤ 3n . Recently, Farhi [1] established ...
