Math 318 Class notes
... Definition. A function is a binary relation f ⊆ A × B such that for any x ∈ A, ∃!y ∈ B such that ( x, y) ∈ f . Alternatively, we can also define a function as a triple ( f , A, B) such that f ⊆ A × B is a function in the previous sense, we write f : A → B, dom( f ) = A, range( f ) = {y ∈ B : ∃ x ∈ A ...

The refinement type, {U nit|P }, is critical. If P is known by constructive evidence p, then the refinement type ...

... which (5) holds. But having identified ϕn with the wff whose Gödel number is n, we replaced (5) by (7); after that we never used the assumption that ‘n’ and ‘m’ range over natural numbers. They can range over some domain, depending on the intended interpretation of the language; syntactic items will ...

Cumulativity and Countability in Karitiana Verbs* Luciana Sanchez
... The sentences with intransitive verbs are in a copular construction. Storto 2009 proposes that copular sentences are bi-clausal structures in Karitiana in which the copula verb aka selects a nominalized small-clause as its complement. These sentences are understood as raising sentences in which the ...

Using the predicate „kind” to give types is a process called reification: (∀x)(∀y )(kind(x, Cat) ∧ kind(y , Fish)) ⇒ like(x, y ) The names of types may have aliases just as the names of individuals can, ...

If ϕ contains no free variables exactly one of ϕ and ¬ϕ is in L, since otherwise both ϕ and ¬ϕ would be satisfied by all sequences. Suppose t satisf ...
