ISBN-13: 9783540346456

This booklet provides chosen themes in technological know-how and engineering from an applied-mathematics viewpoint. The defined typical, socioeconomic, and engineering phenomena are modeled by way of partial differential equations that relate nation variables similar to mass, pace, and effort to their spatial and temporal diversifications. as a rule, those equations are hugely nonlinear; in lots of instances they're structures, they usually signify demanding situations even for the main sleek and complex mathematical and numerical-analytic options. the chosen subject matters mirror the longtime medical pursuits of the writer. They contain flows of fluids and gases, granular-material flows, organic approaches resembling development formation on animal skins, kinetics of rarified gases, unfastened obstacles, semiconductor units, and socioeconomic procedures. every one subject is in brief brought in its medical or engineering context, via a presentation of the mathematical versions within the type of partial differential equations with a dialogue in their simple mathematical houses. the writer illustrates every one bankruptcy by way of a sequence of his personal high quality images, which show that partial differential equations are strong instruments for modeling a wide number of phenomena influencing our day-by-day lives.

The trendy idea of linear differential structures dates from the Levinson Theorem of 1948. it is just in additional fresh years, even though, following the paintings of Harris and Lutz in 1974-7, that the importance and variety of purposes of the theory became favored. This e-book supplies the 1st coherent account of the vast advancements of the final 15 years.

A presentation of the corresponding model hierarchy, the connections of the different PDE models in the hierarchy and a collection of references on the mathematical analysis of kinetic and macroscopic chemotaxis models can be found in [3]. The scaling limit of a phase space chemotaxis model leading to the Keller–Segel model was rigorously analysed in [1]. 4) (after appropriate rescaling). 4) are posed on Rn , n = 1, 2 or 3 and look for solutions such that r decays to 0 as |x| tends to infinity.
