1997 · Universidad Almería

This book provides an up-to-date account of research in Approximation Theory and Complex Analysis, areas which are the subject of recent exciting developments.The level of presentation should be suitable for anyone with a good knowledge of analysis, including scientists with a mathematical background. The volume contains both research papers and surveys, presented by specialists in the field. The areas discussed are: Orthogonal Polynomials (with respect to classical and Sobolev inner products), Approximation in Several Complex Variables, Korovkin-type Theorems, Potential Theory, Ratinal Approximation and Linear Ordinary Differential Equations.

Mexican American Colonization During the Nineteenth Century

by José Angel Hernández

2012 · Cambridge University Press

This study examines various cases of return migration from the United States to Mexico throughout the nineteenth century. Mexico developed a robust immigration policy after becoming an independent nation in 1821, but was unable to attract European settlers for a variety of reasons. As the United States expanded toward Mexico's northern frontiers, Mexicans in those areas now lost to the United States were subsequently seen as an ideal group to colonize and settle the fractured republic.
