This quantity comprises the complaints of the 3rd overseas convention on Deductive and Object-Oriented Databases. Its imperative guiding principle is that the object-oriented and deductive paradigms for modeling, organizing, and processing information supplement one another, instead of competing, and that difficulties related to gigantic volumes of complicated info can top be solved by way of integrating the simplest of either methods.

This quantity comprises the contributions to the Joint German/Austrian Con- rence on Arti? cial Intelligence, KI 2001, which contains the twenty fourth German and the ninth Austrian convention on Arti? cial Intelligence. they're divided into the subsequent different types: – 2 contributions by way of invited audio system of the convention; – 29 authorised technical papers, of which five the place submitted as software papers and 24 as papers on foundations of AI; – four contributions through contributors of the economic day, within which businesses operating within the ?

Let R be a topological ring. Denote by h(R) the minimal infinite regular cardinal number for which there exists a neighborhood V of zero which can be represented as a reunion of a family of cardinality < h(R) of compact subsets. Remark 2. We note that if m is an arbitrary infinite cardinal number then there exist regular cardinal numbers m' such that m < m'. Indeed, let m = H a , where a is an ordinal. Then Ka < H Q+ i and H a + i is a regular cardinal number. We obtain that h(R) is defined for any topological ring.
