Extensions of Rings and Modules

"The authors of this monograph have made important contributions to this subject during the last few decades and they aim to give a comprehensive treatment of the topic. ... Each chapter is followed by brief historical notes. There is a large number of exercises and a bibliography with over 400 entries. This volume fills a gap in the literature and will be an important reference for ring theorists in years to come." (C. Baxa, Monatshefte fur Mathematik, Vol. 180, 2016) "This book is to present the state of the art on the subject, which includes some of the most recent work done on these topics. ... The monograph is as self-contained as possible, with extensive references that are useful for further study. The book is very well written and it can serve as a good tool for graduate students, ting theorists and researchers in algebra and analysis." (J. Jirasko, Mathematical Reviews, September, 2014) "This book is a research monograph intended for research mathematicians and advanced graduate students in ring theory. ... the book is well-organized, well-written and informative. It will be a handy companion for ring theorists in general, but an essential tool for researchers who want to extend our knowledge of extensions, hulls and the transfer of properties between rings and modules and their extensions." (Stefan Veldsman, zbMATH, Vol. 1291, 2014)
