چکیده
A bstract We construct the boundary phase space in D -dimensional Einstein gravity with a generic given co-dimension one null surface $$ \mathcal{N} N as boundary. The associated symmetry algebra is semi-direct sum of diffeomorphisms and Weyl rescalings. It generated by towers charges that are functions over . These can be rendered integrable for appropriate slicings space, provided there no graviton flux through In particular slicing this type, charge direct Heisenberg transverse v any fixed value advanced time Finally, we introduce expansion- spin-memories, discuss memory effects encode passage gravitational waves , imprinted change charges.

The Space of Null Geodesics (and a New Causal Boundary)
The space of null geodesics, G, of a space-time, M, carries information on various aspects of the causal structure M. In this contribution, we will review the space of null geodesics, G, and some natural structures which it carries, and see how aspects of the causal structure of M are encoded there. If M is strongly causal, then G has a natural contact manifold structure, points are represented...
متن کاملA New Method of Mobile Robot Navigation: Shortest Null Space
In this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. The robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (SNS) toward the goal. In the case of no obstacle, SNS was a direct path from the robot to goal; however, in the presence of obstacles, SNS was a space around the r...

متن کاملComparison of null-space and minimal null-space control algorithms
This paper deals with the stability of null-space velocity control algorithms in extended operational space for redundant robots. We compare the performance of the control algorithm based on the minimal null-space projection and generalized-inverse-based projection into the Jacobian nullspace. We show how the null-space projection affects the performance of the null-space tracking algorithm. Th...
