“Schwarzschild spacetime with extra compact dimensions”


címmel tartandó szemináriumára.


Kivonat:



There are two branches of 1+(3+n)-dimensional spacetimes with 
(1+3)-dimensional part corresponding to spherically symmetric spacetime and 
with Euclidean symmetry in n extra dimensions which satisfy vacuum Einstein 
field equations. One branch is a trivial extension of the Schwarzschild 
spacetime, while the second branch is nontrivial. The extra dimensions may be 
compactified, so that, in principle, these solutions may be relevant in our 
(1+3)-dimensional Universe. We will discuss some unusual features of the 
nontrivial case, based on tests through Newtonian limit, Kretschmann scalar 
invariant, and conserved energy defined through Landau-Lifshitz stress-energy 
pseudotensor. These tests indicate some unusual properties.
