Topological Pressure of Free Semigroup Actions For Non-Compact Sets and Bowen’s Equation, II

Journal of Dynamics and Differential Equations, 2020
Inspired to the work of Ma and Wu (Discrete Contin Dyn Syst 31:545–557, 2011) and Climenhaga (Ergodic Theory Dyn Syst 31(4):1163–1182, 2011), we introduce the new notions of topological pressure and upper (lower) capacity topological pressure of a free ...

Note on topological ternary semigroup

, 2020
In this paper, we have discussed various topological properties of (Hausdörff) topological ternary semigroup and topological ternary group. We have proved that the Cartesian product of an arbitrary family of topological ternary semigroups is again a ...

INVARIANT MEASURES ON SEMIGROUPS AND IMBEDDING TOPOLOGICAL SEMIGROUPS IN TOPOLOGICAL GROUPS

Mathematics of the USSR-Sbornik, 1981
In this paper the case of topological semigroups that are cancellative and right reversible is considered. It is shown (Theorem 1) that the existence in such a semigroup of a left invariant measure satisfying certain conditions is equivalent to the imbeddability of some open ideal of the given semigroup as an open subsemigroup in a locally compact ...

Embedding of Countable Topological Semigroups in Simple Countable Connected Topological Semigroups

Journal of Mathematical Sciences, 2001
The main result of the paper is as follows. An arbitrary countable topological (inverse) semigroup is topologically isomorphically embedded into a simple countable connected Hausdorff topological (inverse) semigroup with unit.

Topology of the Semigroup of Singular Endomorphisms

SemiGroup Forum, 2000
\(\text{End}(V)\) is the semigroup of all endomorphisms of an \(n\)-dimensional vector space \(V\) over either the field \(\mathbb{R}\) of real numbers or the field \(\mathbb{C}\) of complex numbers. The subsemigroup of \(\text{End}(V)\) consisting of all singular endomorphisms is denoted by \({\mathbf S}_n\) and it is well known that \({\mathbf S}_n\)

Right-topological semigroup operations on inclusion hyperspaces

Matematychni Studii, 2008
We show that for any discrete semigroup $X$ the semigroup operation can be extended to a right-topological semigroup operation on the space $G(X)$ of inclusion hyperspaces on $X$. We detect some important subsemigroups of $G(X)$, study the minimal ideal,

Compact Topological Inverse Semigroups

Semigroup Forum, 2000
A topological inverse semigroup is a Hausdorff topological space together with a continuous multiplication and an inversion. With every topological inverse semigroup \(S\) one can associate its band of idempotents \(E(S)\). This paper studies compact topological inverse semigroups by relating them to their band of idempotents. Next, we describe briefly

On the measure-theoretic entropy and topological pressure of free semigroup actions

Ergodic Theory and Dynamical Systems, 2016
In this paper we introduce the notions of topological pressure and measure-theoretic entropy for a free semigroup action. Suppose that a free semigroup acts on a compact metric space by continuous self-maps.
