Stone-cech Compactifications via Adjunctions
The Stone-Cech compactification of a space X is described by adjoining to X continuous images of the Stone-tech growths of a complementary pair of subspaces of X. The compactification of an example of Potoczny from [P] is described in detail. The Stone-Cech compactification of a completely regular space X is a compact Hausdorff space ßX in which X is dense and C*-embedded, i.e. every bounded re...
متن کاملRelating Operator Spaces via Adjunctions
This chapter uses categorical techniques to describe relations between various sets of operators on a Hilbert space, such as self-adjoint, positive, density, effect and projection operators. These relations, including various Hilbert-Schmidt isomorphisms of the form tr(A−), are expressed in terms of dual adjunctions, and maps between them. Of particular interest is the connection with quantum s...
متن کاملYaglom Limits via Compactifications
Consider a Markov process X with finite lifetime. In this paper, we derive sufficient conditions for the existence of a Yaglom limit, or limiting conditional distribution for X.
متن کاملOn matrix points in Čech–Stone compactifications of discrete spaces
We prove the existence of (2 , τ)-matrix points among uniform and regular points of Čech–Stone compactification of uncountable discrete spaces and discuss some properties of these points.
متن کاملnew semigroup compactifications via the enveloping semigroups of associated flows
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
