This is the first book to be dedicated entirely to profinite groups, an area of algebra with important links to number theory and other areas of mathematics. It provides a comprehensive overview of the subject; prerequisite knowledge is kept to a minimum, and several major theorems are presented in an accessible form. The book would provide a valuable introduction for postgraduate students, or form a useful reference for researchers in other areas. The first few chapters lay the foundations and explain the role of profinite groups in number theory. Later chapters explore various aspects of profinite groups in more detail; these contain accessible and lucid accounts of many major theorems. Prerequisites are kept to a minimum with the basic topological theory summarized in an introductory chapter.

He had to keep moving, that the man instinctively knew. He had to get away, from the rioting, the lawlessness, the killing. Away from the brutal gangs that ruled the highways. Then there was the boy that he found along the way, an orphan with no place to go. He couldn't leave the child behind; that would be murder. Together they had to make their way across the razed landscape of post collapse America, west to where there was safety, a chance to begin again. If only they survived the journey.

3,822 perimeter miles. 11,247 rivers and streams. 8,749 feet at its height. 268,596 square miles in total. Texas is big. Julius Caesar once quipped that all of ancient Gaul could be divided up into three parts. Texas resists such easy division. Mapping Texas, edited by John S. Wilson, presents an array of early maps, dating from 1561 to 1860. The volume features selections from the extensive material housed in the Frances C. Poage Map Room of The Texas Collection at Baylor University. The painstaking labors of Spanish, French, English, and Mexican mapmakers illustrate the progressive and differing views of Texas geography and boundaries. Originally used as guides to new destinations, these maps also staked new claims, fueled by new dreams, on new territory that settlers had heard about but never seen. Page by page, Texas' iconic shape gradually emerges. As now-familiar cities dot this vast expanse of land, railroads trace the outline of rivers and mountain ranges, and ports anchor the curve of the Gulf of Mexico, Texas' rich history comes to life one map at a time. The volume concludes with an analysis of map art and cartouches - beautiful images that both name the map and highlight flora and fauna. A sumptuous delight for mind and eye, this volume lavishly documents the early outlines of the land over which six flags have proudly flown.
