Conformal invariants (conformally invariant tensors, conformally covariant differential operators, conformal holonomy groups etc ) are of central significance in differential geometry and physics Well-known examples of such operators are the Yamabe-, the Paneitz-, the Dirac- and the twistor operator The aim of the seminar was to present одебф the basic ideas and some of the recent developments around Q-curvature and conformal holonomy The part on Q-curvature discusses its origin, its relevance in geometry, spectral theory and physics Here the influence of ideas which have their origin in the AdS/CFT-correspondence becomes visible The part on conformal holonomy describes recent classification results, its relation to Einstein metrics and to conformal Killing spinors, and related special geometries.  Чайный набор2010 г Мягкая обложка, 164 стр ISBN 3764399082.
