Groups Associated with Minimal Flows

چکیده
Let S be topological semigroup, we consider an appropriate semigroup compacti cation b S of S. In this paper we study the connection between subgroups of a maximal group in a minimal left ideal of b S, which arise as equivalence classes of some closed left congruence, and the minimal ow characterized by the left congruence. A particular topology is de ned on a maximal group and it is shown that a closed subgroup under this topology is precisely the intersection of an equivalence class with the maximal group for some left congruence on b S.

Mapping of Agricultural Information Flows for Yam Minisett Technology in Delta State, Nigeria
ABSTRACTThis study examined information flow on minisett technology among yam farmers in Delta State, Nigeria. A sample size of 180 respondents was involved in the study. Data were obtained from respondents of the study through the use of a validated interview schedule. Percentage, frequency count and mean scores were used to summarize data, while line diagrams were used to develop maps of info...
متن کاملOn minimal flows, definably amenable groups, and o-minimality
We study definably amenable groups in NIP theories, focusing on the problem raised in [10] of whether weak generic types coincide with almost periodic types, equivalently whether the union of minimal subflows of a suitable type space is closed. We give fairly definitive results in the o-minimal context, including a counterexample.
متن کاملCharacterizations of Regular Almost Periodicity in Compact Minimal Abelian Flows
Regular almost periodicity in compact minimal abelian flows was characterized for the case of discrete acting group by W. Gottschalk and G. Hedlund and for the case of 0-dimensional phase space by W. Gottschalk a few decades ago. In 1995 J. Egawa gave characterizations for the case when the acting group is R. We extend Egawa’s results to the case of an arbitrary abelian acting group and a not n...
متن کاملPolish groups with metrizable universal minimal flows
We prove that if the universalminimal flow of a Polish groupG ismetrizable and contains a Gδ orbit G · x0, then it is isomorphic to the completion of the homogeneous space G/Gx0 and show how this result translates naturally in terms of structural Ramsey theory. We also investigate universal minimal proximal flows and describe concrete representations of them in a number of examples.
متن کاملROBUST RESOURCE-CONSTRAINED PROJECT SCHEDULING WITH UNCERTAIN-BUT-BOUNDED ACTIVITY DURATIONS AND CASH FLOWS II. SOUNDS OF SILENCE: A NEW SAMPLING-BASED HYBRID PRIMARY-SECONDARY CRITERIA HARMONY SEARCH METAHEURISTIC
In this paper, we present a new idea for robust project scheduling combined with a cost-oriented uncertainty investigation. The result of the new approach is a makespan minimal robust proactive schedule, which is immune against the uncertainties in the activity durations and which can be evaluated from a cost-oriented point of view on the set of the uncertain-but-bounded duration and cost param...
