Does the cosmological constant imply the existence of a minimum mass?
C. G. Boehmer, T. Harko
We show that in the framework of the classical general relativity the presence of a positive cosmological constant implies the existence of a minimal mass and of a minimal density…
On inflation and torsion in cosmology
Christian G. Boehmer
In a recent letter by H. Davoudiasl, R. Kitano, T. Li and H. Murayama ``The new Minimal Standard Model'' (NMSM) was constructed that incorporates new physics beyond the Minimal Sta…
A note on dilaton gravity with non-smooth potentials
Christian G. Boehmer, Piotr Bronowski
Recent interest in brane world models motivates the investigation of generic first order dilaton gravity actions, with potentials having some non-smoothness. We consider two differ…
Static perfect fluid balls with given equation of state and cosmological constant
Christian G. Boehmer
Static and spherically symmetric perfect fluid solutions of Einstein's field equations with cosmological constant are analysed. After showing existence and uniqueness of a regular…
