Gravitation Model

ABSTRACT Examination of recent information about tourist journeys outside Quebec Province has given rise to the idea that such trips do not take place in accordance with conventional laws such as those based on the universal gravitation model, but rather are governed by criteria of decision in which distance is not a continuous variable. After emphasizing certain weaknesses of conventional models of spatial interaction, this article shows that the theory of catastrophes, developed from R. Thom's studies of morphogenesis, makes possible a new approach, based on utilitarian concepts, to the role played by distance in tourist journeys.

Gravitation Model

We show that in the RN gravitation model, there is no dynamical symmetry breaking effect in the formalism of the Schwinger-Dyson equation (in flat background space-time). A general formula for the second variation of the gravitational action is obtained from the quantum corrections hμν (in arbitrary background metrics).

Gravitation Model

It is common practice in business geography to use gravity models such as the Reilly’s Retail Law of Gravitation model to gauge the extent of presumed trade areas for retail sites based on a variable that models the general demographic attractiveness of the site in question. In the Huff retail model, an exponent represents additional attractiveness factors that differentially affect certain sites; however, it is less common practice to vary the attractiveness of one site alone and to visually inspect in a series of maps the differences in other trade areas given the variation of assumptions about the attractiveness of that site. The idea behind this form of analysis is that business managers benefit from being able to visualize a range of possible contingencies to which they may have to respond. The city of New Britain, Connecticut, is used as a demonstration model in this article to provide these kinds of visualization maps.
