Five-Dimensional Space-Times

A brane in five - dimensional Minkowski space ∗

We discuss the propagation of gravity in five-dimensional Minkowski space in the presence of a four-dimensional brane. We show that there exists a solution to the wave equation that leads to a propagator exhibiting four-dimensional behavior at low energies (long distances) with five-dimensional effects showing up as corrections at high energies (short distances). We compare our results with pro...

A brane in five - dimensional infinite flat Minkowski space ∗

We discuss the propagation of gravity in five-dimensional infinite flat Minkowski space in the presence of a four-dimensional brane. Previous analyses have modeled the propagation of gravity in the extra dimensions by imposing boundary conditions on the brane equivalent to considering incoming waves on both sides of the brane. By considering, instead, incoming waves on one side of the brane, wh...

Time-dependent gravitating solitons in five-dimensional warped space-times

Time-dependent soliton solutions are explicitly derived in a five-dimensional theory endowed with one (warped) extra dimension. Some of the obtained geometries, everywhere well defined and technically regular, smoothly interpolate between two five-dimensional anti-de Sitter space-times for a fixed value of the conformal time coordinate. Time-dependent solutions containing both topological and n...

FUZZY HV -SUBSTRUCTURES IN A TWO DIMENSIONAL EUCLIDEAN VECTOR SPACE

In this paper, we study fuzzy substructures in connection withHv-structures. The original idea comes from geometry, especially from thetwo dimensional Euclidean vector space. Using parameters, we obtain a largenumber of hyperstructures of the group-like or ring-like types. We connect,also, the mentioned hyperstructures with the theta-operations to obtain morestrict hyperstructures, as Hv-groups...
