Model theoretic aspects of the Ellis semigroup
Let G be a group definable in a theory T . For every model M of T , the space SG(M) of the complete G-types over M is a G M -flow. We compare the Ellis semigroups related to the flows SG(M) and SG(N) when M ≺ ∗ N , focusing particularly on the groups into which the minimal left ideals in these semigroups split. In the case where T is an o-minimal expansion of the theory of reals and G is defina...

15 صفحه اولOn the shadowing property of nonautonomous discrete systems
In this paper we study shadowing property for sequences of mappings on compact metric spaces, i.e. nonautonomous discrete dynamical systems. We investigate the relation of weak contractions with shadowing and h-shadowing property.
متن کاملOn Nonautonomous Discrete Dynamical Systems Driven by Means
We investigate the asymptotic behavior of nonautonomous discrete dynamical systems governed by the system of difference equations (recursive equations): yj(n+ 1) = Fj(n, y(n)); j = 1, . . . ,k, n = 0,1,2, . . . , where y(n) = (y1(n), . . . , yk(n)) ∈ Rk, y(0) = x, and Fj(n,·) is a mean of k (≥ 2) positive real numbers, that is, a real-valued function satisfying the internality property min(x)≤ ...
متن کاملThe Index of a Quantum Dynamical Semigroup
A numerical index is introduced for semigroups of completely positive maps of B(H) which generalizes the index of E0-semigroups. It is shown that the index of a unital completely positive semigroup agrees with the index of its dilation to an E0-semigroup, provided that the dilation is minimal. Introduction. We introduce a numerical index for semigroups P = {Pt : t ≥ 0} of normal completely posi...
