چکیده
In this paper, it is shown that for d ∈ ℕ, a minimal system (X, T) d-step pro-nilsystem if its enveloping semigroup top-nilpotent group, answering an open question by Donoso. Thus, combining the previous result of Donoso, turns out and only group.

On Tame Enveloping Semigroups
A dynamical version of the Bourgain-Fremlin-Talagrand dichotomy shows that the enveloping semigroup of a dynamical system is either very large and contains a topological copy of βN, or it is a “tame” topological space whose topology is determined by the convergence of sequences. In the latter case we say that the dynamical system is tame. We show that (i) a metric distal minimal system is tame ...
متن کاملEnveloping Semigroups in Topological Dynamics
This is a survey of the theory of enveloping semigroups in topological dynamics. We review the, already classical, theory of enveloping semigroups, due mainly to Robert Ellis, and then proceed to describe some new connections which were discovered in the last few years between three seemingly unrelated theories: of enveloping semigroups, of chaotic behavior, and of representation of dynamical s...

متن کاملEnveloping algebras of the nilpotent Malcev algebra of dimension five
Pérez-Izquierdo and Shestakov recently extended the PBW theorem to Malcev algebras. It follows from their construction that for any Malcev algebra M over a field of characteristic 6= 2, 3 there is a representation of the universal nonassociative enveloping algebra U(M) by linear operators on the polynomial algebra P (M). For the nilpotent non-Lie Malcev algebra M of dimension 5, we use this rep...
متن کاملOn nilpotent subsemigroups in some matrix semigroups
We describe maximal nilpotent subsemigroups of a given nilpotency class in the semigroup Ωn of all n × n real matrices with nonnegative coefficients and the semigroup Dn of all doubly stochastic real matrices.
