Sommario/riassunto |
|
This book addresses the subject of gravity theories in two and three spacetime dimensions. The prevailing philosophy is that lower dimensional models of gravity provide a useful arena for developing new ideas and insights, which are applicable to four dimensional gravity. The first chapter consists of a comprehensive introduction to both two and three dimensional gravity, including a discussion of their basic structures. In the second chapter, the asymptotic structure of three dimensional Einstein gravity with a negative cosmological constant is analyzed. The third chapter contains a treatment |

Sommario/riassunto |
|
A small group of freethinkers from the Dutch Republic played a key role in the major intellectual changes of the Early Enlightenment (1640-1720).In the wake of Cartesianism, their rationalist ideas transformed debates about science, theology, medicine, and political theory. |
