Taschenbuch. Condition: Neu. Neuware -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 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.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 164 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This is the first systematic account of the main results in the theory of lightlike submanifolds of semi-Riemannian manifolds which have a geometric structure, such as almost Hermitian, almost contact metric or quaternion Kähler. Using these structures, the book presents interesting classes of submanifolds whose geometry is very rich.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 488 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -In der Bundesrepublik Deutschland überwachen die Behörden der Länder die Einhaltung der Vorschriften, die für das Inverkehrbringen und die Anwendung von Pflanzenschutzmitteln gelten.Mit dem Pflanzenschutz-Kontrollprogramm wurde ab 2004 eine länderübergreifende Initiative zur Verbesserung der Überwachung pflanzenschutzrechtlicher Vorschriften eingeführt. Ziel ist ein bundesweit harmonisiertes Verfahren bei der Durchführung und Berichterstattung der Kontrollen. Das Programm wird nach gemeinsamen Standards auf Grundlage eines abgestimmten Handbuches durchgeführt. Die Festlegung von Kontrolltatbeständen und die Betriebsauswahl erfolgt durch die Länder; zusätzlich werden jährlich bundesweite Schwerpunktkontrollen festgelegt. Der vorliegende Bericht fasst die Ergebnisse des Jahres 2008 zusammen. 32 pp. Deutsch.
