Conformal Differential Geometry Q-Curvature and Conformal Holonomy

From the reviews:

“This book grew out of an Oberwolfach student seminar on recent developments in conformal differential geometry which took place in 2007. It splits into two chapters, which to a large extent are independent of each other. Each of the chapters is an extended version of a series of lectures presented by one of the authors during the seminar and offers a nice and easily readable survey of an active area of research in conformal differential geometry.” (Andreas Cap, Mathematical Reviews, Issue 2011 d)
