Failures of Categoricity and Compositionality for
... The news is not all good for the modest inferentialist. The meaning generated by Garson’s method for disjunction has a pair of undesirable properties. It is not categorical in the sense above of not uniquely extending an assignment of semantic values to the atomic sentences of a language and it is n ...

... which case Γω ⊢ ∆ω is the “limit union” of the sequents along this branch. • Either way, we show Γω ⊢ ∆ω is not provable (this uses the trace condition). • Thus we can use Γω ⊢ ∆ω to construct a syntactic counter-model (the inductive predicate case also uses the ...

Proof Theory - Andrew.cmu.edu
... Contemporary logic textbooks often present formal calculi for first-order logic with a long list of axioms and a few simple rules, but these are generally not very convenient for modeling deductive arguments or studying their properties. A system which fares better on both counts in given by Gerhard ...

CPS130, Lecture 1: Introduction to Algorithms
... I feel this is justified. For example, when I taught cps 196, Discrete Mathematics, Fall 2001, some students who had already taken cps130 did not feel entirely comfortable with this material. To make the presentation more interesting, and perhaps a bit unique, I will do propositional logic and Boole ...

We denote with v P the boolean function associated with P , i.e. vP : {0, 1}n → {0, 1} is defined as follows: for each (a 1 , . . . , an ), ai ∈ {0, 1}, there exists i ∈ {1, . ...
