"The main intent of this short volume is to provide a largely self-contained and broadly accessible exposition of two cosmological applications of algebraic quantum field theory (QFT) in curved spacetime. ... There is a very long reference list at the end of each chapter and the overall impression is that the author transmits a great deal of information about this subject in a brief volume." (Paul F. Bracken, Mathematical Reviews, April, 2016)
