Theory of regions

1998
The synthesis problem for nets consists in deciding whether a given graph is isomorphic to the marking graph of some net and then constructing it. This problem has been solved in the literature for various types of nets ranging from elementary nets to Petri nets.

Region-Based Theories of Space

2012
This chapter focuses on the topological and mereological relations, contact, and parthood, between spatio-temporal regions as axiomatized in so-called mereotopologies. Despite, or because of, their simplicity, a variety of different first-order axiomatizations have been proposed. This chapter discusses their underlying ontological choices and different

Theories of Regional Imbalance

1976
Bibliographies of recent studies on the regional problem are not notable for their reference to Marx. There may be a variety of reasons for this. One undoubtedly is the extent to which many ‘regional economists’ take their theoretical terms of reference (like their professional training) from mainly neo-classical sources.

The Theory of Photoionized Regions

2003
In this chapter, we move from considering plasmas that are excited by predominantly collisional means to those that are heated by energetic photons coming from a photoionizing source, be it a star, a nucleus of an active galaxy, or whatever. Such photoionization-dominated plasmas are very commonly observed in galaxies and historically, were one of the ...

Dominatarian Theory of Regional Integration

Insight on Africa, 2020
In this article an alternative thinking and methodological approach for the study of regional integration is proposed, addressing the limitations of classical regional integration theories and the new regionalism approach. A ‘dominatarian’ theory is introduced as an alternative analytical framework that exposes meanings attributed to a social force ...

Region-Based Theory of Space: Algebras of Regions, Representation Theory, and Logics

2007
In this paper, we present recent results in the region-based theory of space that concern algebras of regions, the corresponding topological and discrete models, and representation theory. We also discuss applications to Qualitative Spatial Reasoning (QSR), an actively developing branch of AI and Knowledge Representation (KR).

An Economic Theory of Regional Clusters

Journal of Urban Economics, 2000
This paper investigates the impact of localization economies on firms' locations. It is known that such external effects lead to substantial cost reductions when firms are located together. However, when they are agglomerated, firms also face the prospects of tough price competition whose intensity can be relaxed through product differentiation.

Theories of Regional Self-Balance

1976
For various reasons, classical economists were not much concerned with the regional distribution of activity. For one thing, it was assumed that capital and labour would migrate to those areas in which they would earn the highest attainable profit or wage.
