RELATIVE INFORMATION FUNCTIONAL OF RELATIVE DYNAMICAL SYSTEMS
In this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. We extract the information function ofan ergodic dynamical system (X,T) from the relative information of T fromthe view point of observer χX, where X denotes the base space of the system.We also generalize the in...
متن کاملOn the data complexity of relative information completeness
Databases in an enterprise are often partially closed: parts of their data must be contained in master data, which has complete information about the core business entities of the enterprise. With this comes the need for studying relative information completeness: a partially closed database is said to be complete for a query relative to master data if it has tuples either does not change its a...
متن کاملRelative Completeness for Logics of Functional Programs
We prove a relative completeness result for a logic of functional programs extending D. Scott’s LCF. For such a logic, contrary to results for Hoare logic, it does not make sense to ask whether it is complete relative to the full theory of its first-order part, since the first order part does not determine uniquely the model at higher-order types. Therefore, one has to fix a model and choose an...

متن کاملCompleteness of integrated information sources
For many information domains there are numerous World Wide Web data sources. The sources vary both in their extension and their intension: They represent different real world entities with possible overlap and provide different attributes of these entities. Mediator-based information systems allow integrated access to such sources by providing a common schema against which the user can pose que...
