Krishan L. Duggal,Aurel Bejancugical revolution. Just like steam and electricity, the diffusion of those ‘general-purpose technologies’ in all sectors of activity modifies not only the products, but also the organization of production and the way of life. Nevertheless, their ‘added value is based on the manipulation and diffusion

Krishan L. Duggal,Aurel Bejancus. Hence, the European ICT sector accounts for 5 percent of gross domestic product, and contributes to productivity growth in a 20 percent (European Commission, 2010). Services are increasingly being delivered online. And for more and more people the internet has become a major component of their da

Algebraic Preliminaries,e material should be familar to the reader, but we stress with a quasi-orthonormal basis induced by degenerate subspaces, which some readers may find unfamiliar. In particular, we included the null tetrad formalism, used in relativity, the linear isometries of semi-Euclidean spaces and their semi-or

Differential-Geometric Structures On Manifolds,bundles and introduce the main differential operators: Lie derivative, exterior differential, linear connection, general connection. Distributions on manifolds (known as non-holonomic spaces in classical terminology) are then introduced and studied by using both methods of vector fields and of diffe

Lightlike Hypersurfaces of Semi-Riemannian Manifolds,uce a non-degenerate screen distribution and construct the corresponding lightlike transversal vector bundle .(.) of ., consistent with the well-known theory of Riemannian submanifolds. This enables one to define the induced geometrical objects such as linear connection, second fundamental form, sha
