Degradation in probability logic: When more information leads to less precise conclusions

Christian Wallmann, Gernot D. Kleiter (2014)

Similarity:

Probability logic studies the properties resulting from the probabilistic interpretation of logical argument forms. Typical examples are probabilistic Modus Ponens and Modus Tollens. Argument forms with two premises usually lead from precise probabilities of the premises to imprecise or interval probabilities of the conclusion. In the contribution, we study generalized inference forms having three or more premises. Recently, Gilio has shown that these generalized forms “degrade” – more...

On a problem of Steve Kalikow

Saharon Shelah (2000)

Fundamenta Mathematicae

Similarity:

The Kalikow problem for a pair (λ,κ) of cardinal numbers,λ > κ (in particular κ = 2) is whether we can map the family of ω-sequences from λ to the family of ω-sequences from κ in a very continuous manner. Namely, we demand that for η,ν ∈ ω we have: η, ν are almost equal if and only if their images are. We show consistency of the negative answer, e.g., for ω but we prove it for smaller cardinals. We indicate a close connection with the free subset property and its variants. ...
