... are called + and ·. p → q is more troublesome. The important thing to note is that if p is false, p → q is true! Example 6. p := “108 is the largest number in the world”, q := “7 is prime”. Then: p ∧ q is false, and p ∨ q is true. What about p → q? It’s true! You could think of it as being “if p is ...

... We say that a sequence Q satisfies a formula cp (or cp is true for a) if (o,O) + cp, which will be abbreviated as g + cp. A formula cp is oalid, denoted k cp (or simply cp when it is clear that validity is intended), if cp is satisfied by every sequence. Quantification deserves special attention. Ea ...

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