1. Chomsky heirarchy 2. Popularization of Transformational Grammer. 3. The Pumping Lemma 4. Chomsky Normal form 5. Many different Grammatical theories all involving math to some degree or
another.
If Chomsky chooses not to use quantitiative math in his work its because
he think the point is easier made otherwise or he is biased. While he personally stopped doing math fairly early, to my extemely rusty knowledge he's more competant than most, mostly in mathematical logic. Just another one of the mans many accomplishments.
