Sommario/riassunto

This volume provides a complete description of ASL variation. People from varying regions and backgrounds have different ways of saying the same thing. For example, in English some people say "test," while others say "tes'," dropping the final "t." Noted scholars Ceil Lucas, Robert Bayley, and Clayton Valli led a team of exceptional researchers in applying techniques for analyzing spoken language variation to ASL. Their observations at the phonological, lexical, morphological, and syntactic levels demonstrate that ASL variation correlates with many of



the same driving social factors of spoken languages, including age, socioeconomic class, gender, ethnic background, region, and sexual orientation. Internal constraints that mandate variant choices for spoken languages have been compared to ASL as well, with intriguing results.

Sommario/riassunto

This engaging text describes the development of singular perturbations, including its history, accumulating literature, and its current status. While the approach of the text is sophisticated, the literature is accessible to a broad audience. A particularly valuable bonus are the historical remarks. These remarks are found throughout the manuscript. They demonstrate the growth of mathematical thinking



on this topic by engineers and mathematicians. The book focuses on detailing how the various methods are to be applied. These are illustrated by a  number and variety of examples. Readers are expected to have a working knowledge of elementary ordinary differential equations, including some familiarity with power series techniques, and of some advanced calculus. Dr. O'Malley  has written a number of books on singular perturbations.  This book has developed from many of his works in the field of perturbation theory.
