Domain wall solution in $F(R)$ gravity and variation of the fine structure constant
solution gravity variation fine structure
2011/10/18
We construct a domain wall solution in $F(R)$ gravity. We first compare a scalar field theory having a runaway type potential with a corresponding scalar field theory obtained through a conformal tran...

2009/2/26
The Stellingwerf one-zone stellar model is extended by assuming,
a slow and uniform rotation that leads to a very small oblateness of the star. The
matter in the core-surrounding shell is suposed to...
