From the reviews: "...the present book is a coherent, unified, and very readable entity. Throughout the discussion is clear, informative, and natural. It can be recommended as a book to read, as well as to consult, after a basic exposure to hybrid logics. The book ends with a somewhat philosophical discussion... I will not try to summarize ... Read morethe author’s points. I will say I enjoyed the discussion. And the book." Melvin Fitting The Graduate School and University Center City University of New York New York, USA “This book grew out of nine research papers of the author, two of which are coauthored by T. Bolander and, respectively, V. de Paiva. The papers were converted into harmonically synchronized chapters of the book, which will certainly appeal to the reader … . The book contains lots of corresponding results, covering all important cases. … Undoubtedly, Braüner’s monograph fills a gap in the hybrid logic literature in a desirable way.” (Bernhard Heinemann, Zentralblatt MATH, Vol. 1217, 2011) Show Less
