Umbilicity of (Space-Like) Submanifolds of Pseudo-Riemannian Space Forms

We study umbilic (space-like) submanifolds of pseudo-Riemannian space forms, then define totally semi-umbilic space-like submanifold of pseudo Euclidean space and relate this notion to umbilicity. Finally we give characterization of total semi-umbilicity for space-like submanifolds contained in pseudo sphere or pseudo hyperbolic space or the light cone.A pseudo-Riemannian submanifold M in (a...

Size Matters: Logarithmic Space Is Real Time

We show that all the problems solvable by a nondeterministic machine with logarithmic work space (NL) can be solved in real time by a parallel machine, no matter how tight the real-time constraints are. We also show that several other real-time problems are in effect solvable in nondeterministic logarithmic space once their real-time constraints are dropped and they become non-real-time. We thu...

The Emerging Customary Law of Space

Theoretical Framework for People's Space Rights From the Perspective of Jurisprudence and Islamic Law

Urban space in the present age is a finite and very limited commodity, which is justly exploited in the area of ​​emerging jurisdiction in the field of architectural and urban law. By applying this penal law to the discretion, the measurement can be made by using effective services, in the public space of the city. Users of architecture, adding special Brosbin, (virtualization that can be done ...
