Pattern Formation in Spatial Economicseneric theory of differential equations is used to topologically characterize those patterns that are structurally stable, and the transitions among them are then studied by the elliptic and hyperbolic umblic catastrophes.CHASE 发表于 2025-3-27 09:09:18
Some Reflections on the Relation Between Economic Theory and Empirical Realityparticular cases of empirical generalizations, as the hypotheses on the lowest abstraction levels are called. The empirical generalizations must contain magnitudes which have, explicitly stated or tacitly understood, operational definitions by which they can be calculated on the bases of measurements of directly observed magnitudes.explicit 发表于 2025-3-27 12:23:55

Puu‘s thinking on cultural economics and his views on the methodology of economic science are also luckily exposed by the papers in this volume. Readers interested in the spatial dimension of the economy will find original ideas on the optimal allocation of road capital.978-3-642-64596-9978-3-642-60877-3needle 发表于 2025-3-27 18:14:10

Personal safety and well-being,d product. Land, capital and labour are available within the region, whereas energy is imported. The location pattern resulting from structural stability is studied. Afterwards umbilic castrophesresulting from changes of, e.g., energy prices are discussed in detail.要求比…更好 发表于 2025-3-28 13:25:48
Brief Interventions for Psychosislag system. Moreover, the action of the accelerator is made non-linear as suggested by Goodwin. This changes the system to produce limit cycles. The limit cycles may bifurcate due to parametric change. In the spatial setting it is seen that the space coordinates can cause bifurcation of the temporal limit cycle pattern.
