A group G is said to be sharply 2-transitive if it has an action on a set X with at least 2 elements such that, for all pairs (x, x') and (y, y') of distinct elements in X, there exists […]

Reem Yassawi     "Tame or wild Toeplitz shifts" The Ellis semigroup E(X, T) of a topological dynamical system is defined to be the compactification of the action T in the topology of pointwise convergence on the space of all […]
