چکیده

For a compact Hausdorff space X, let J be the ordered set associated with of all finite open covers X such that there exists nJ, where nJ is dimension ∂. Therefore, we have Hˇp(X;Z), 0≤p≤n=nJ. continuous self-map f on α∈J an cover and Lf(α)={Lf(U)|U∈α}. Then, fiber L˙f(α) Xf induced by Lf(α). In this paper, define topological entropy entL(f) as supremum ent(f,L˙f(α)) through Xf={Lf(U);U⊂X}, Lf(U) f-fiber U, images fn(U) preimages f−n(U) for n∈N. prove conjecture logρ≤entL(f) being given ρ maximum absolute eigenvalue f*, which linear transformation Čech homology group Hˇ*(X;Z)=⨁i=0nHˇi(X;Z).

Milnor’s Conjecture on Monotonicity of Topological Entropy: results and questions∗

Theorem (Milnor and Thurston [MT77], see also [MT88]). The function C → R which associates to a mapping g ∈ C its topological entropy htop(g) is continuous. Here C stands for C maps of the interval with b non-degenerate critical points (non-degenerate means second derivative non-zero). This theorem relies on a result of Misiurewicz and Szlenk, see [MS77, MS80] who had previously shown that γ(f)...

Black Hole Entropy, Topological Entropy and the Baum-Connes Conjecture in K-Theory

We shall try to exhibit a relation between black hole entropy and topological entropy using the famous Baum-Connes conjecture for foliated manifolds which are particular examples of noncommutative spaces. Our argument is qualitative and it is based on the microscopic origin of the Beckenstein-Hawking area-entropy formula for black holes, provided by superstring theory, in the more general nonco...

Entropy operator for continuous dynamical systems of finite topological entropy

In this paper we introduce the concept of entropy operator for continuous systems of finite topological entropy. It is shown that it generates the Kolmogorov entropy as a special case. If $phi$ is invertible then the entropy operator is bounded with the topological entropy of $phi$ as its norm.

The Topological Cyclic Deligne Conjecture

Let O be a cyclic topological operad with multiplication. In the framework of the cosimplicial machinery by McClure and Smith, we prove that the totalization of the cosimplicial space associated to O has an action of an operad equivalent to the framed little 2-discs operad.

The topological Rohlin property and topological entropy

For a compact metric space X let G = H(X) denote the group of self homeomorphisms with the topology of uniform convergence. The group G acts on itself by conjugation and we say that X satisfies the topological Rohlin property if this action has dense orbits. We show that the Hilbert cube, the Cantor set and, with a slight modification, also even dimensional spheres, satisfy this property. We al...
