The third edtion is an update on the second edtion, which was published in 1985. New material will focus on matrix population models. Since 1985, these models have been developed into a very general and powerful approach to studying population growth and structure.

Drawing data from official sources in 60 countries, as well as from the United Nations and the World Bank, this compendium of statistical information on population, fertility, and mortality treats every one of the UN-recognized countries in at least summary form. With data from 1950 onward and projections through 2020, this volume extends the dataset of Nathan Keyfitz and Wilhelm Flieger’s landmark work, World Population: An Analysis of Vital Data (1968), with virtually no overlap. All the life tables, standardized rates, and projections have been generated by uniform methods to ensure e

This volume will be of interest to applied mathematicians, to researchers in Partial Differential Equations, and to those involved in Fluid Dynamics and Numerical Analysis examining models for viscoelastic flows, porous medium and granular flows, and flows exhibiting phase transitions. As papers in this volume indicate, physical processes whose simplest models may involve change of type occur also in other dynamic contexts, such as in the simulation of oil reservoirs, involving multiphase flow in a porous medium, and in granular flow.

The calculus of variations is a beautiful subject with a rich history and with origins in the minimization problems of calculus. Although it is now at the core of many modern mathematical fields, it does not have a well-defined place in most undergraduate mathematics curricula. This volume should nevertheless give the undergraduate reader a sense of its great character and importance. Interesting functionals, such as area or energy, often give rise to problems whose most natural solution occurs by differentiating a one-parameter family of variations of some function. The c
