This book deals with Riemannian manifolds for which the nullity space of the curvature tensor has codimension two. These manifolds are ?semi-symmetric spaces foliated by Euclidean leaves of codimension two? in the sense of Z I Szab¢. The authors concentrate on the rich geometrical structure and explicit descriptions of these remarkable spaces. Also parallel theories are developed for manifolds of ?relative conullity two?. This makes a bridge to a survey on curvature homogeneous spaces introduced by I M Singer. As an application of the main topic, interesting hypersurfaces with type number two in Euclidean space are discovered, namely those which are locally rigid or ?almost rigid?. The unifying method is solving explicitly particular systems of nonlinear PDE.
This volume contains invited lectures and selected research papers in the fields of classical and modern differential geometry, global analysis, and geometric methods in physics, presented at the 10th International Conference on Differential Geometry and its Applications (DGA2007), held in Olomouc, Czech Republic.The book covers recent developments and the latest results in the following fields: Riemannian geometry, connections, jets, differential invariants, the calculus of variations on manifolds, differential equations, Finsler structures, and geometric methods in physics. It is also a celebration of the 300th anniversary of the birth of one of the greatest mathematicians, Leonhard Euler, and includes the Euler lecture ?Leonhard Euler ? 300 years on? by R Wilson. Notable contributors include J F Cari¤ena, M Castrill¢n L¢pez, J Erichhorn, J-H Eschenburg, I Kol ?, A P Kopylov, J Korba?, O Kowalski, B Kruglikov, D Krupka, O Krupkov , R Landre, Haizhong Li, S Maeda, M A Malakhaltsev, O I Mokhov, J Mu¤oz Masqu, S Preston, V Rovenski, D J Saunders, M Sekizawa, J Slov k, J Szilasi, L Tam ssy, P Walczak, and others.
This volume publishes the papers given by invitation at the fifteenth Congress of the International Organization for the Study of the Old Testament, which was held at Cambridge in July 1995, under the Presidency of J.A. Emerton. The articles cover a wide range of subjects relevant to the study of the Old Testament, and reflect the ongoing debate on a variety of themes among the world's leading contemporary Old Testament scholars.
This study presents intriguing analysis of the impact of private security companies' practices upon the fields of security and politics in the Czech Republic. It situates cases concerning ABL, the biggest Czech private security company, in the larger social, political, legal and economic contexts of the booming private security business. This company's extensive linkages with Czech politics suggest that the continued absence of specific legislation for the regulation of private security companies' activities is due to too much, rather than too little, political interest in their activities. This is problematic, arguably, because the practices of private security companies have already contributed to a significant transformation of the Czech security field by enhancing the commodification and depoliticization of security, while ABL's use of security methods for political purposes and a business approach to politics have profoundly transformed the field of politics. Reflecting the growing interest in the privatization of security, this timely study unpacks the relationship between politics, business and security in the Czech Republic.
