Compatible flat metrics

Journal of Applied Mathematics, 2002
We solve the problem of description of nonsingular pairs of compatible flat metrics for the general N-component case. The integrable nonlinear partial differential equations describing all nonsingular pairs of compatible flat metrics (or, in other words,

Centre?periphery model explaining the regional development of the informational and transitional society [PDF]

This paper analyses regional development and uses centre-periphery models (CPM) of Friedmann, Gibbs and Hautamäki as a base for theoretical discussion. In general, these centre-periphery models foresee stabilisation and de-concentration of population and

Effects of rotation scheme on fishing behaviour with price discrimination and limited durability: Theory and evidence. [PDF]

, 2004
This paper examines how rotation arrangement between two groups of fishers with different institutional arrangements affects fishing behaviour and economic outcomes in a particular economic environment characterised by price discrimination and product ...

Quantizing a non-locally massive 2-form model

Physics Letters B
A non-local yet gauge-invariantly massive 2-form model is considered that leads to local and unitary dynamics upon proper gauge-fixing. Since canonical momenta cannot be defined owing to the non-locality, consistent quantization of this system warrants ...

MHD oscillatory channel flow, heat and mass transfer in a physiological fluid in presence of chemical reaction

Alexandria Engineering Journal, 2016
In the present paper, the problem of oscillatory MHD flow of blood in a porous arteriole in presence of chemical reaction and an external magnetic field has been investigated. Heat and mass transfer during arterial blood flow are also studied.

Flow of a Bingham fluid in a porous bed under the action of a magnetic field: Application to magneto-hemorheology

Engineering Science and Technology, an International Journal, 2017
The study deals with an investigation of the flow of a Bingham plastic fluid in a porous bed under the action of an external magnetic field. Porosity of the bed has been described by considering Brinkman model.
