Syndetic set — In mathematics, a syndetic set is a subset of the natural numbers, having the property of bounded gaps : that the sizes of the gaps in the sequence of natural numbers is bounded. DefinitionLet mathcal{P} f(mathbb{N}) denote the set of finite… … Wikipedia
Piecewise syndetic set — In mathematics, piecewise syndeticity is a notion of largeness of subsets of the natural numbers. Let mathcal{P} f(mathbb{N}) denote the set of finite subsets of mathbb{N}. Then a set S sub mathbb{N} is called piecewise syndetic if there exists G … Wikipedia
IP set — In mathematics, an IP set is a set of natural numbers which contains all finite sums of some infinite set.The finite sums of a set D of natural numbers are all those numbers that can be obtained by adding up the elements of some finite nonempty… … Wikipedia
Partition regular — In mathematics, the notion of partition regularity in combinatorics is one approach to explaining when a set system is quite large.Given a set X, a collection of subsets mathbb{S} subset mathcal{P}(X) is called partition regular if for any A in… … Wikipedia
