... Definition 2.4 (Union and intersection). The union A ∪ B of two sets A and B is defined by A ∪ B = {x : x ∈ A or x ∈ B}. Note that ‘or’ in mathematics means ‘and/or.’ The intersection A ∩ B is defined by A ∩ B = {x : x ∈ A and x ∈ B}. Sometimes infinite unions come useful. For example, the set of al ...

... In S5, we have reduction of modalities, especially here we use the fact that ϕ ↔ ϕ, and get using normality (ϕ → ψ) → (ϕ → ψ) that ⊢ (K p ∨ K ¬p) → (p → K p). (NK) follows by two applications of modus ponens in the last formula. So, Von Wright states: It used to be one of the disputed ...

... As a consequence we obtain the following: Corollary 14. Let σ ∈ Lω1 ω . a) If σ has a definably rigid model then σ has a countable rigid model. b) If every countable model of σ is rigid then all models of σ are definably rigid. We remark that the only property of K = M od(σ) needed for the Corollary ...
