Følner, Banach, and translation density are equal and other new results about density in left amenable semigroups

Daniel Glasscock, Neil Hindman, Dona Strauss

In any semigroup $S$ satisfying the Strong Folner Condition, there are three natural notions of density for a subset $A$ of $S$ : Folner density $d (A)$ , Banach density $d^{*} (A)$ , and…

Combining extensions of the Hales-Jewett\\ Theorem with Ramsey Theory\\ in other structures

Neil Hindman, Dona Strauss, Luca Q. Zamboni

The Hales-Jewett Theorem states that given any finite nonempty set $\A$ and any finite coloring of the free semigroup $S$ over the alphabet $\A$ there is a {\it variable word\/} ov…

Duality for image and kernel partition regularity of infinite matrices

Neil Hindman, Imre Leader, Dona Strauss

A matrix A is image partition regular over Q provided that whenever Q - {0} is finitely coloured, there is a vector x with entries in Q - {0} such that the entries of Ax are monoch…

Recurrence in the dynamical system $(X, ⟨ T_{s} ⟩_{s \in S})$ and ideals of $β S$

Neil Hindman, Dona Strauss, Luca Q. Zamboni

A {\it dynamical system\/} is a pair $(X, ⟨ T_{s} ⟩_{s \in S})$ , where $X$ is a compact Hausdorff space, $S$ is a semigroup, for each $s \in S$ , $T_{s}$ is a continuous functio…
