On IP* sets and central sets


IP* sets and central sets are subsets of ℕ which are known to have rich combinatorial structure. We establish here that structure is significantly richer that was previously known. We also establish that multiplicatively central sets have rich additive structure. The relationship among IP* sets, central sets, and corresponding dynamical notions are also investigated.
