Non-extremal Localised Branes and Vacuum Solutions in M-Theory
Non-extremal overlapping p-brane supergravity solutions localised in their
relative transverse coordinates are constructed. The construction uses an
algebraic method of solving the bosonic equations of motion. It is shown that
these non-extremal solutions can be obtained from the extremal solutions by
means of the superposition of two deformation functions defined by vacuum
solutions of M-theory. Vacuum solutions of M-theory including irrational powers
of harmonic functions are discussed.Comment: LaTeX, 16 pages, no figures, typos correcte
On Principle of Inertia in Closed Universe
If our universe is asymptotic to a de Sitter space, it should be closed with
curvature in in view of dS special relativity. Conversely, its
evolution can fix on Beltrami systems of inertia in the dS-space without
Einstein's `argument in a circle'. Gravity should be local dS-invariant based
on localization of the principle of inertia.Comment: 13 page
On Torsion-free Vacuum Solutions of the Model of de Sitter Gauge Theory of Gravity (II)
It is shown that all torsion-free vacuum solutions of the model of dS gauge
theory of gravity are the vacuum solutions of Einstein field equations with the
same positive cosmological constant. Furthermore, for the gravitational
theories with more general quadratic gravitational Lagrangian (), the
torsion-free vacuum solutions are also the vacuum solutions of Einstein field
equations.Comment: 4 pafes,0 figur
