Syntax 1 Wiki: Week 3

Exercise 1 For I(cat1) and I(lilly), specify one plausible value each so that the formula cat1(lilly) becomes true in M.
Check your answer
I(cat1) = {<cat1>,<cat2>,<cat3>}
For I(lilly), each of the following 3 values will now make cat1(lilly) true in M:
a. I(lilly) = cat1 , or
b. I(lilly) = cat2 , or
c. I(lilly) = cat3 .
We prove this for case (b):
1. [[cat1(lilly)]]M = 1 iff <[[lilly]]M> ∈ I(cat1)
2. iff <I(lilly)> ∈ I(cat1)
3. iff <cat2> ∈ {<cat1>,<cat2>,<cat3>}
Hence: since (3) is the case, so are (2) and the righthand side of (1). Finally, since the righthand side of (1) is the case, the lefthand side is the case as well. Hence [[cat1(lilly)]]M is true in model M. That is what we intended to prove!
