Beschreibung:
This book surveys the differential geometry of varieties with degenerate Gauss maps, using moving frames and exterior differential forms as well as tensor methods. The authors illustrate the structure of varieties with degenerate Gauss maps, determine the singular points and singular varieties, find focal images and construct a classification of the varieties with degenerate Gauss maps.
In this book, the authors study the differential geometry of varietieswith degenerate Gauss maps. They use the main methods of differentialgeometry, namely, the method of moving frames and exteriordifferential forms as well as tensor methods. This book is intendedfor researchers and graduate students who are interested in projectivedifferential geometry and algebraic geometry and their applications.
